You're amazing my teacher had 2 hours with me and he barley helped I wish you were my 7th grade teacher
Me too
I have to learn this in year 5 I’m in Australia and I need this to help when I get older so when I do it’s a lot easier
I learn this in grade 5
@Lucas Hahn just to remind my self something I have a test coming up
Same
FOR EVERYONE NEW HERE:
This video is correct in everything he says!
There are people below who don't know anything so don't listen to them. The guy making this video didn't explain some bits very well but if you know basic stuff about it, you will understand.
Thanks man
In his video picture he put a problem he didn’t even use... he puts them on but don’t even explain half of them..
The sum of all the angles is 180 degrees not 360 degrees in a triangle. He said it was 360 degrees at 11:00
@@user-dh2ee3ht6m at 11:00 he said "the angle of the full circle is 360" not of the triangle
THANK YOU SO MUCH OMG I HAVE A MATHS TEST TMR AND I HAD NO IDEA ABOUT WHAT THIS WAS BUT YOU SAVED ME!!! GOD BLESS YOU 🙏🏽🙏🏽❤️❤️ YOU JUST EARNED A NEW SUBSCRIBER
Thank you so much for the help. My 6+ math homework was rough until you came in an made so much sense!
I had a six page math worksheet all about polygons dew 1 hour and this helped so much but all tho i has 2 more questions left i had the most done in class this helped a lot thank you ☺️
Jdo
Thank you so much. I have a math test tomorrow and I had no idea how to do this so, thank you.
MR. Organic Chemistry Tutor, thank you for another exceptional video/lecture on the Area of Shaded Region. These are all well-known figures/shapes that are the heart and soul of modern Geometry.
This guy is one of the best tutors on youtube if not the best, if you dont understand him its definitely on you.
Very helpful as usual keep doing more videos of this
This is needed! Thank you 🙏
Thx this helped alot with my assignment
I did not understood the hard parts but thnx it was helping me a lot
Man i wish you were my teacher, you explained this better than our actual lesson. Thank you!
exactly bro my teacher barely explained and she didnt even show us the formula 💀
Thanks for teaching i needed this for the math competition
Good luck!
You saved my grades thanks 🙏
It's still difficult but thx for the help it still helps a little bit 😀
Yea, I'm sorry but, he's kinda too fast and well i had a difficult time catching up since we just started this lesson😀
Thanks for doing my homework 😁
literally teachers make this shit so complicated and than complain when we do something wrong thank you bro
Thank you 💖
Thank you so much
Thank you, this video is so helpful! 😊🥰🥺
Thank yooooou!!!
i love your teaching but i had difficulty of the 2 last ones but tnx i love u
I have a test tomorrow and he helped a lot
Thanks broo, u helped me at my exam night
Bro u carried🙏🏾 5th grade math class was easy now
Thanks for this I'm glad you maked this video:-)
This is so easy now tysm 😊😊😊😊😊
Very very nice explanation 🙂 sir
It is a great help
good job i needed this
this guy deserves more subs who agrees?
Me
i had no clue about this now i fully understand
Can this be done for irregular shapes too because i am a bit confused if you can or can not
diagonal of a rectangle doesnt bisect interior angles unless the rectangle is a square
sir what is the problem if i calculate the shaded area of square inside rectangle as (8-5)(10-5) for the first example
man u deserve more than 5 million subs
he has 7mil now. sry for late ahh response
2:53 , if 64 x 3.14 is equal to 200.96, therefore 400-200.96 = 199.04 right? Why it is 198.9? I'm confused
same thing I was thinking too
He didn't use 3.14 as pi, instead he calculated it directly on calculator using the pi in calculator. I hope u get what I mean.
Thank you dude!
In 5:48 that is not a rectangle. Its a square. Because W=8 and L=8...
lol my brain is too small for this
XD also mine 😅
its so complicated but i managed hahaha
Thank you so much sir
love your vids
Thanks this helps
I had downloaded it for weeks but never watched it and was always leaving the question like last one in paper. Today I got disconnected from internet and decided to watch and guess what PROBLEM SOLVED 1.5 marks secured
i have a question. Can we multiply pie with the number? if i do it during my exam will i lose marks?
Yes you can multiply pie with the no. If you do not do it you will lose marks
I am in class 5 and I really appreciate you I am preparing for my exams
man u make math look easy
Can you go over a question circle inside a rectangle height is 10 cm width this 10 cm what is the area?
wrong he used the pie symbol instead of the reg 3.14 instead of pie that goes on forever
3.14 x 64 is 200.96 and then u subtract that from 400 which is 199.04
its true so show us the true way
He used a calculator to do that you could hear him typing on the calculator if you wear headphones
it takes my teacher to spend hours on this and I wouldn't get it but now I get it in minutes
11:40, how do you know that its 2 at the slope, while its half at 1 at the height and Square root of 3 at the length?
WOW THIS HELPS
mine has an expression in it. inside a big rectangle there is a small rectangle and its height is a-6 while the width is only a, what should i do? can someone help?
in 9:05, why couldnt we just get the area of the square as (5 x 5 = 25) since the side is 5 cm already in length, then subtract it to the area of the bigger square 64 (8x8=64) to get 39?
7:45, how do we know that this is right angle because what if this is paralleogram?
thank you
I hate my life because of math
how did you get the answer on the sercel in the cube sorry i dont now how to spell correctliy
This is so helpful I am in 5th grade. Writing common entrance and am going to pass
AMAZING
would’ve been more helpful if you did some squares with variables in them
How do i know if i need to add the answers or subtract them?
Keywords/what's asked in a question ex:
You need to find the area of a square but there's a circle, find the area of the circle and the square and subtract becuz you're finding the area of the square
I have a question sir why you didn't calculate the value of π when the answer was 33π
for example 2 circle 1 one what if we do not have a radius
Thank u
Thanks! But I can't understand the last question pls help me
i just want to know where is the rectangle in a rectangle tho
????
Noticed that your videos have very low volume. That may be the only issue for now
Im in 6th grade and im in pre algebra but my teacher is not very good and i don’t understand with the way she teaches but tou are so good at teaching thank you do much
I am in 7th grade and I am from Ethiopian in Africa 🌍
can u do how to find unshaded area region ☹️
1:10 where did you get the 25? Pls answer me
He got the 25 from multiplying the 5 x 5 from the square, since to find the area of the square you multiply side x side, which would be the two 5s from the square.
I didn't get 4:01??
I thought of a better and easier way to solve the last problem, you just do radius multiplied by the square root of 12 which gives the length of one side of the triangle which we divide by two to get half of the base, then we multiply that by the square root of 3 which give the height, then we multiply that height by half the base to get the area of the triangle, then just subtract the area of the circle to get the shaded region
how did you get 49 from 7 times 3.14 or pie how
oh wait you dont use the pie you use the square
Do you know how to find the radius if not given?
Find diameter I assume
You can find the radius if you know the area or the circumference with the formulas
Area = pi * radius²
Circumference = 2 * pi * radius
Need centimeter for shaded part
My teachers said use 3.14 as PI, where am I supposed to use that at?
Using 3.14 just makes it easier if you don’t have a calculator or something
@@tauheed6550 oh ok, thanks!
@@vvvken1 But if you do have a calculator all you need to do is Shift x10* If you know what I mean
@@tauheed6550 no, I don’t lol
@@vvvken1 On the top of the calculator there’s a button named Shift which flips some stuff around the calculator( have you noticed some yellow equations on top of some buttons?) and near the 0 number there a button which reads x10* and that essentially creates the pi symbol
What if the outer circle has no radios and the inner has a radius of 21
Genius
Thxso
I got a Entrance exam tom and i dont understand math at all💀
What if you don't know the radios of the circle?
Then find it
I don't understanding
How did you turn 400 - 64 into a decimal?
He didnt subtract 64 he subtracted 64π which is 64x3.14 because π is 3.14 so he basically subtracted the product of 64π not 64.
So smart thank you
app please
Why did u make it look easy
I’m in grade 5 lol and I’m learning this
at the time 2:50
what's the formula?
Square: Side x Side
Rectangle: Length x Width
Triangle: Base x Height ÷ 2
Circle: πr²
Please more
Thank you i finally got passed 1.
Lol
At 2:39, He Didn't Use 3.14 To the 64.
Because the pi sign resembles 3.14
Yeah of course
I think you forgot to multiply the 64 inyo pie
The sum of all the angles is 180 degrees not 360 degrees in a triangle. You said it was 360 degrees at 11:00
Dude why would u have a circle with a square on your thumbnail but not include it in the video??? Thats the only reason im here is for that problem.
Shaded Area = pi*radius^2 - s^2
He didn't have to include it in the video because you can apply these other problems with the circle/square shaded area.
@@hisoka9509 what’s the s stand for
@@Spartan-tx6nr the area of a square
@@hisoka9509 thank you
youtube is my teacher!🤣
I just wrote an entire page on how to solve for the shaded area of the circle with the right triangle inside it and it got deleted because the stupid copy and clip button are right next to each other, who the hell had the bright idea of doing this?!
I’m new to this but when he puts 20 why does he put the square root 3
Go watch this video of his th-cam.com/video/w8wdKOsUD-4/w-d-xo.html. It is the geometry introduction video. He explains everything you need to know here, and he also includes the answer for your question. Good luck!
