#volumeofsphere How to derive formula of volume of sphere|| गोले का आयतन 📚✏I hope u all like this video so dont forget to like👍 share & subscribe🔔my channel.so that u can get the notification of next videos... thankyou🙏🙌
@@kpk5928 for 9th students you have no way except proving it experimentally using a cylinder or writing observations 5-6 time and then finding proportionality constant btw i too am 10th
Sir I have a doubt sir agar jitna height and radius sphere or cone ka hai utne height and radius ka agar ham ek cylinder le le sir to volume 1/2πr^2h ho sakta hai kya
But why u take cylinder dear It's a lab activity,mathematically in this activity volume of sphere is equal to volume of two cone 😊 No need of cylinder is there
Sir, this formula can be easily derived by Calculus method, I mean by Integration. First we take an element dV = 4πx² dx and after integrating this function with proper limits, we get our result. Here is full derivation, dV = 4πx² dx ∫dV = ∫ 4πx² dx V = 4π x³/3 After putting limits from 0 to r, we get V = 4/3 πr³
for people wondering what he did , he just added all the hollow spheres volume (surface area ) from 0 to r 4 pi r^2 is just the surface area derived from this: 2(int(2 pi r )) from 0 to r [adding the rings (circumference) both up and down it will give you 4 pi r^2 the surface area of a sphere you’re welcome
With the help of an activity observe that what will be the effect on volume of a sphere, if its radios is tripled Sir please bata do ki activity kaise hogi class10
Thanks sir ab hame pata chal gaya
Bhut vadiya 👍👍Thanks sir
Welldone explanation sir
Sir It was so easy.. Thank You😊
Thanks
bahut badiya ❤❤❤❤
Welcome
Bhut achhe se smjh aya.. Very helpful vedio 😊 😊
My pleasure👍
Hii
Asome trick
Sir your method is much good because this is helpful
Thankyou so much
Thank you sir
Superb explanation sir 👍🏻👍🏻😊
Great❤❤❤
Thankyou
Without Taking two cones volumes can you derive the volume of sphere formula ??
do it by integration there are multiple ways
I am asking for 9th standard students. Integration method is for 12th standard students only

How the volume of sphere is sum of the volumes of two cones?
Aap ne b tou gota hi bata diya
Nice explanation sir 🙏🙏🙏
Thanks, it helps me to convince my students
One of the teacher on TH-cam who gives comment on their students comments 😅❤
Yes offcourse 😊
Why volume of sphere must be equal to the sum of volume of two cones of equal radius and height...??
its easy to understand thank u sir ❤🙏
its so simple to understand thankyou so much sir
Thank u so much sir...it was so easy to understand...😊
Thanks sir
Blessings🙏
Nice
Sir how did you make sure that the volume of the sphere = to the volume of a cone of same height and radius
Its practical activity you can do like the same...
@@DESERVEPOINTACADEMY But how to explain except practical activity..
Super
👌 excellent
🤗
So nice explanation
Thankyou so much
How do you know Volume of sphere = 2 cone volume which radius equal to radius of sphere?
It's practically proved
Lab activity it is
Lab activity kaha hai btao...... Link share kro
Sir volume of sphere 2 volume of cone with same height kyu kiya
Thx sir☺
nice explanation sir
Good explanation
Sir I have a doubt
sir agar jitna height and radius sphere or cone ka hai utne height and radius ka agar ham ek cylinder le le sir to volume 1/2πr^2h ho sakta hai kya
But why u take cylinder dear
It's a lab activity,mathematically in this activity volume of sphere is equal to volume of two cone 😊
No need of cylinder is there
@@DESERVEPOINTACADEMY sir cylinder solid shape wala lpg cylinder nahi 😄😄 why will I say lpg cylinder sir..😂
Nice video
Nice video👌
It's really nice way to explain....👌
Good job
Hm cone hi kyu lenge ye to sir aapne btaya hi ni
It's a practical lab activity
Thank you so much sir
Your welcome
Thankyou sir
Thanks
Sir 1 by 3 apne kisi liya wo sirf samjhao pls

Most welcome
Sir u can’t understand what you say but your pen was good thankyou
Sir thanks.
It really supported in my exams of science.😀
Same
Class 7 ho timi

Sir volume of sphere mein hmlog 2 cone ko kaise liye sphere ke shape mein to koi cone bn hi nahi rha hai
Its a lab practical activity dear👍
Kyu hai 2 cone ke volume ke barabar kon batayega ye
This was the simplest explaination thank you!
Your most welcome
💓🇮🇳🇮🇳
Thanks sir.
Thanks sir 😊😊
Sr volume of sphere, 2 times volume of cone ke equal kaise aaya
It's a practical activity dear
Dono cone me jitna pani ayega utna paani ek sphere me ayega akela.
Exactly👍
Hats offff
Thankyou
👍🏻
Thanks a lot sir ji
After seeing your video, I became your big fan "GURU" 💕💕💕
My pleasure👍
Sir traingle chapter lab samjhao ge
H=2r तो है किंतु त्रिभुज की ऊंचाई aor गोले की ऊंचाई बराबर कैसे हो सकती है,,, अभी ये गलत है,, दो त्रिभुज का योगफल एक गोला कैसे होगा
Tq so much sir
Sir this not proper explanation h= 2r is wrong
You deserve 109k like
Thankyou so much
Sir, h=2r/2=r.
As u took cones from center of sphere.
Whare is H gon
Is this pappus guldinus theorem

Thankyou so much for alternate method👍
for people wondering what he did , he just added all the hollow spheres volume (surface area ) from 0 to r
4 pi r^2 is just the surface area derived from this:
2(int(2 pi r )) from 0 to r [adding the rings (circumference) both up and down
it will give you 4 pi r^2 the surface area of a sphere
you’re welcome
Toh calculas k duniya main jaa ke apna knowledge jhaar na..idhar k elementary school main oversmart dikhata hai
@@RJ-ns6gf true
But this is not for middle level students,they don't know about integration
Nice sir .. sir aap kaha se ho?
I m from bhopal MP
Volume of the cone kaha sai aya
Uska bhi separate derivation hai aap dekh sakte hai channel par
With the help of an activity observe that what will be the effect on volume of a sphere, if its radios is tripled
Sir please bata do ki activity kaise hogi class10
Sir bato ki activity kaise hogi
I didn't get logic
Can you explain about torispherical dish volume
🙄🙄🙄 derivation??
Sir humne toh integration se kiya hai
Dear but 9th 10th class students didn't know the integration
Yes sir I agree with you, your method is the most appropriate for 9th and 10th graders
@namanrai681 thankyou so much Naman
Firstly you should have explained how a sphere amounts to two similar cones.
It is practical activity
Thankyou Sir! What's your name?

No it's innaqurate
Please use integration
Integration??
Sir pls use equal to sign instead of this imply sign
