good Lord! I just had this argument (online) with some supposed math teacher. 22/7 is not π. pi is an irrational number meaning it never ends. it starts out with 3.14159... and continues forever. 22/7 is 3.14285... stop teaching that it is the same. if you measured the diameter of a real life circle that is exactly 44cm in circumference, the diameter would NOT be exactly 14cm. although it would be very very close it's not exact.
A 44 in circumference alluminum disk cut with CNC was off about 4 thousandths of an inch in diameter. Not a big deal I realize but still, the idea with math is to be as accurate as possible so why not use the most accurate formula you can. If you are just getting in the ballpark sure use whatever but if your teaching its the same, that's not correct.
May be I wasn't clear enough. Did you measure the perimeter of a round object with an accuracy up to four digits, to calculate Pi in the follow? Of course not any object but one where you know the circumference is regular. Break Discs, CDs, something like that.
Yes the disk we cut was less than a thousandth of an inch off 44in circumference measured with 3 different CNC machines all saying the exact same value. Funny part is the computer told us before hand what the diameter would be and it was dead on lol.
What a joke!!!!!! This man is trying to proove that the value of pi is 22/7 but while calculating the circumfurence he is taking pi as 22/7 . Are you kidding me ?!?!?!
I could prove that Pi is equal to 2 with a similar method: a circle has radius 1, given that Pi = 2, the circumference is 4. Pi = circumference/(2*radius) =4/2=2. Its like saying Pi is equal to 2 because Pi is equal to 2. You can't assume the value of something that you're trying to prove in your proof.
The error comes at 0:56. He assumed that he measured it at exact 22.0 but the circumference, if you would use more precise tool, should be 21.991... The ratio 22/7 could be used conveniently for many a practical purposes but should not be taught by someone who poses as a math teacher. This video is misleading and irresponsible.
The approximate that I like better is 355/113. That gives you all the accuracy you're likely to need in any practical project. I also like the mnemonic "May I have a large container of coffee?"
C can never be assumed or accurately measured physically. You have to use pi. The best derivation would be to use polygons with incresing number of sides and calculating its perimeter by dividing it into triangles then arriving at the ratio of perimeter to side of triangle. Because polygon with infinite number of sides apporaches a circle.
Would some kind person please indicate to me how, at 01:00 this gentleman found that a circle with diameter 7cm has a circumference of 22cm. as I thought, that at that point, he did not know that pi was 22/7! and he was going to explain why pi =22/7.

Because π is constant , it's basically a formula of circumference / diameter the ratio is approximately equal to 3.14 No matter how big or small your circle is and 3.14 can be written has 22/7 (approximately not exactly)

It would be better if he just got the students to measure the diameters (D) and circumferences (C) of a number of different circles and compare their results when they divide C/D. Alternatively draw a circle with a compass and then marvel at how you can mark the circumference with six points using the radius of the compass to form a hexagon. The space between the two points of a hexagon face and the circle means that Pi must be greater than 3 (i.e. 6/2). This is the method that Archimedes used by extending the number of the sides of the polygon within the circle from 6 to 12, to 24, to 48 to 96 and measuring the lengths of the sides of each new polygon using Pythagoras's theorum. But he did NOT prove Pi nor did he get a finite number. He got a number that was greater than 3 10/71 but less than 3 1/7.
As stated here pi equals 22/7 (or 3 1/7). But the Greek mathematician Archimedes (who by the way lived more than 2000 years ago and without the benefit of calculus) has calculated pi to be LESS than 3 1/7.
@@adnankhan-op1vq pi is not rational, it's irrational and transcendental, so it cannot be expressed as a fraction. 22/7 is just correct to 3 significant digits, which is far from the real thing.
A good teacher will start out at 3.1415926 or 3.14 (as 314/100) because the 100 unit of measure diameter circle will have a circumference of 314.15926... unit appeoximate measurement if it could be measured so accurately. So using 314/100 as a better quotient relationship, in integers representing this circumference to diameter of circles relationships by the scaler defined as π we can move further in a proof that 22/7 best approximates 314/100 (or even 314.15926...). This way the correct math processes were used to arrive at π = 22/7 is a good enough approximation to the circumference to diameter ratio of any circle (unit of length to be considered independent in math calculations).
You want prove that Pi isn't 22/7? Put 22/7 into a calculator and you get 3.14285... I don't know if anyone noticed but that isn't the same as 3.141592...

π≠22/7: quoting Wikipedia, "fractions such as 22/7 are commonly used to approximate π, but no common fraction (ratio of whole numbers) can be its exact value" (π is an irrational number). (en.m.wikipedia.org/wiki/Pi)
If we don't know the value of Pie Sir ..then how could we find the circumference..and why Pie is included in the formula of circumference or others..clear this point..if you can
π is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 are commonly used to approximate π, but no common fraction (ratio of whole numbers) can be its exact value).
Why 22/7? It is better than 31/10 although the denominator 7 is less than 10. To get the approximation, write π=3+1/7.0625...≈3+1/7=22/7. For a better approximation, write π=3+1/(7+1/15.9969...)≈3+1/(7+1/16)=355/113
Sorry Sir, but I have just a question : π=3,141592... But 22/7=3,142857... So you say that 3,141592...=3,142857... ? I'm sorry, but are you a mathematics' teacher ? Sorry for some mistakes, I'm from France
Being an irrational number, π cannot be expressed as a common fraction (equivalently, its decimal representation never ends and never settles into a permanently repeating pattern). Still, fractions such as 22/7 and other rational numbers are commonly used to approximate π
The diameter and circumference can NOT both be rational numbers. Your example only works if you round the circumferences to integer values before calculating pi.
He finds the circumference with the assumption that pi = 22/7. But the whole issue with pi is accuracy! 22/7 is an approximation! Archimedes method is the easiest to understand.
Using 22/7 as pi from any teacher of math is very sad. Close but no banana. We strive to teach the concrete, not the approximate. You did give a proof, sir, but I think not the one you wanted.

The value of pi is not actually 22/7 but for ease of calculation and quick analysis we generally take it as an approximation of 22/ 7.

You are chasing a delusion. Quoting, and referring us to another delusional person is not a proof that your delusion is factual. The golden ratio is obviously the square root of 5, plus 1, and 1/2 of that. The golden ratio also is obviously the ratio of a "very large" fibonacci number divided by the one immediately smaller than it. It is quite easy to belabouraously examine those divisions and notice what phi converges at to any accuracy one desires(why did you stop at 34/21, lol?). . You can go on and on with things like replacing the real pi with some other "pi", and finding something smoothly falling into place. But unfortunately for you, it is easy to evolve pi with, for instance, Archies simple, rational method, and pi always comes out to, well, what pi actually is. You are only impressing yourself. Btw, the typical methods to use phi to calc pi, are not really that at all. They are really, just use of pi to calc pi.
+Slim: Question, are you lonely? Every school child knows what phi is, how it is derived, just as is true for pi. Also, there is no connection between pi and phi. At least, anyway, YOUR "connection" is not a connection. The fact that the sine of 54 deg is exactly 1/2 of pi, is not "a connection between pi/phi. That "quarter circle", blah, blah, blah, "calc" of pi, while intriquing, is not "using phi to calc pi", as the length of any circle or a part of a circle already involves pi. To calc pi using such things is only employing pi to calc pi. "Circular", pardon the pun
Good one but, how did he get the value of circumference mathematically if value of pi was unknown at first place ie. how did he say circumference of 7cm dia. is 22
He didnt get the value mathematically. He just measured the circumference and got 22. But if he used a more precise measuring tool, the value he would get should get would be 21.99115.. Close, but not 22.0 This is where the error starts.
Ur wrong Pi is not equal 22/7 22/7 is approximately pi not equal. There are other methods to compute pi. Which will give u 3.14... 22/7 is a good approximation because. Take 3.14 substract 3 and take the inverse of it.Amd do it repeatedly. And finally reverse it.U will get this π=3+1/7 after doing this once Do again π=3+1/(7+(1/15+...)) This will go on however we approximate it by only taking it upto 1/7 So u get π is approx 3+1/7 or (21+1) /7 or 22/7

The golden ratio also is obviously the ratio of a "very large" fibonacci number divided by the one immediately smaller than it. It is quite easy to belabouraously examine those divisions and notice what phi converges at to any accuracy one desires(why did you stop at 34/21, lol?). . You can go on and on with things like replacing the real pi with some other "pi", and finding something smoothly falling into place. But unfortunately for you, it is easy to evolve pi with, for instance, Archies simple, rational method, and pi always comes out to, well, what pi actually is. You are only impressing yourself. Btw, the typical methods to use phi to calc pi, are not really that at all. They are really, just use of pi to calc pi.
+Slim: Question, are you lonely? Every school child knows what phi is, how it is derived, just as is true for pi. Also, there is no connection between pi and phi. At least, anyway, YOUR "connection" is not a connection. The fact that the sine of 54 deg is exactly 1/2 of pi, is not "a connection between pi/phi. That "quarter circle", blah, blah, blah, "calc" of pi, while intriquing, is not "using phi to calc pi", as the length of any circle or a part of a circle already involves pi. To calc pi using such things is only employing pi to calc pi. "Circular", pardon the pun
(-; Btw, that "every school kid" thing is of course, not true. Also, don't ever put away your fascination with these things ......
You have some really, really basic visualization problems, Slim. You sure you didnt ride the short bus to gradeschool???
Ok y u choose the diameter 7,14,21,28
and pi is defined like A wheel starts rotating from 0 when it completes one rotation it ends up in 3.14159
The value of pi is slightly lesser than the mathematical value of 22/ 7. In fact, the absolute value of pi is still unknown.
But what is the real value of π in calculator 3.1415 like that we see how to find
π represent construction of project, eg-a polygon with different length and bredth,finding perimeter with even and odd number,(3+x).
That is why India is to not able produce any genius.... thanks to genius like him...
Sir you don't explained how to use 22/7......
In fact ,pi is not equal to 22/7 . But, pi approximate 22/7, 22/7 is greater than Pi.
what's sound quality 😖
It's time to calculate my circular head circumference
LOL
😁😊🤣
I'm going to take the high road and allow this man his moment in the spotlight.

What are you saying sir?the formula of circumference of circle is 2piR and you are using whatever you want... It's wrong..
Good one but, how did he get the value of circumference mathematically if value of pi was unknown at first place
ie. how did he say circumference of 7cm dia. is 22
shut the fuck up moron
He didnt get the value mathematically. He just measured the circumference and got 22. But if he used a more precise measuring tool, the value he would get should get would be 21.99115.. Close, but not 22.0 This is where the error starts.
Sir, very good
You did a mistake that you wrote circumference of third circle as "C4"
Aravind Chukka how come you got 185 subs without content?
How pie come th-cam.com/video/hizcbicm_qo/w-d-xo.html
In what country is PI = 22/7 ?
what if change value 22 for 23 or 21
Why the circumference = 22 in 7cm circle
Ur wrong
Pi is not equal 22/7 22/7 is approximately pi not equal. There are other methods to compute pi. Which will give u 3.14... 22/7 is a good approximation because. Take 3.14 substract 3 and take the inverse of it.Amd do it repeatedly. And finally reverse it.U will get this
π=3+1/7 after doing this once
Do again
π=3+1/(7+(1/15+...))
This will go on however we approximate it by only taking it upto 1/7
So u get
π is approx 3+1/7 or (21+1) /7 or 22/7
when you dont know value of pi then how could you calculated circumference
Circumferences are not 22, 44, 66, 88. You actually need the digits. Hence proof is wrong. Please fix ASAP.
If diameter is
Why we take only diameters that is multiple of 7?????
This is not the right way to describe the value of pi
Sir, pie is not equals to 22/7, it is nearly equals to 22/7. Pie is a irrational number. 22/7 is a rational number.
Wat rubbish..... How u got the values of C as 22,44,66,88.. By substituting pie as 22/7...n again u r repeating the loop.. Pls dnt provide wrong info... Its a request
how u calculate circumference
