It's nice to learn and it is easy to understand
Question is still remains same that why lateral surface area of cylinder is equal to surface area of sphere.
@Naveen praveen xD
But I want to know that derivation
Because sphere has no top and bottom faces it is round
Yeah
Area of sphere = lateral surface area of cylinder
4pie r²= 2pie rh we know height =diameter which is equal to double radius so height= 2r
4pier²=2pie r(2r)
4pier²=2pie2r² (2 common)
4 pie r ²= 4pie r ²
Hence proved.
Hope u understood this😊
Thank you for your video. Is there a way for you to illustrate why the lateral area of a cylinder is the same as the surface area of a sphere? I do not understand any intuitive relationship between them, and it is difficult for me to imagine why I would end up with a sphere if I folded down (infinitely many) slices to the middle of a cylinder.
I have the exact same question 🤔🤔🤔
Really it was an awesome video,👏👏 easy to understand the concepts of sphere👍 keep it up 👌
Thank you for your clear explanation of surface area for sphere. Really appreciate it!!!!
Thank You Greg for your valuable comment.
Stay Tuned, Enjoy Learning with Letsute.
Sir if surface area of sphere will not be equal to the lateral surface area then what will be the surface area of sphere??
Dimple, Lateral surface area and the total surface area in the case of sphere is same. As the entire surface is same, there are no edges to divide the surface area like in the case of a hemisphere. I hope this will clear your doubt.
Hy
Suppose we consider sphere in two dimensional arrangements and stacked closer to each other then how much surface area of the plain surface is occupied how can we relate this to radius of sphere ?
I'll get back to you
thats excellent, your work is short and precise,this makes it so understandable
Sir, kya sphere me curved surface area bhi hota hai,?? Plz give me answer

we can make all sizes stainless steel sphere . www.stainless-steel-sphere.com
Ur teaching technique is good... amazing
Hey Priyanka,
Thankyou so much for appreciating our work.
Sir, please tell how lateral surface area of sphere is equal to surface area of sphere
Please answer
I looked everywhere for this until i come here thank you sir. I understood at the first shot. Looking frwrd for more videos like this
thanks for the wonderful explanation sir.
Cool, thanks for that!
Made me understand better.
Thank u👍😀😀
It was really helpful. Thank you very much!!!😊
Happy to know that our videos were helpful to you.

can you explain more on how come the lateral surface area of cylinder equals to surface area of sphere?
thx
@Naveen praveen proof Jan na chahiye...na ..ratne se koi concept nahi.....smjhoge bhaii....aaur jo Janna chahta hai wo to question to karega...
Mind blowing

It will help students to easy learning
Keep it up

Hii
Md Mohsin Ansari Gregg murder
@@tamizuddinansari7609 huh?
I am dubious about hemisphere. as I am preparing for compitive exams. one should clear basics concepts and I am very thankful to you.. 🙏
Hey Neeraj Dhanik,
Thanks for the comment.
We also believe the same concept of clearing the basics before moving ahead and we make our content in such a way that any person can understand it.
Do watch our other videos too.
I knew that the earth was a flat surface. What's left of the radius in the sphere/cylinder, is what's called the firmament. With that being said, there are no planets out there neither, I'm sure.
I thought that you were going to do the math on a half hollow sphere, which would really explain our earth. You should do that and make a video about the earth in this manner!
I came here for the first time and received what I was looking forward to learning. Thanks.
Superb sir,, very easy way ....thanx..
Thank you for your appreciating comment. Keep watching, Keep learning!
but how can the lateral area of the cylinder equal the surface of the sphere? if we How can that work in this case, but not with a circle and a line?
I am unable to understand how anybody can dislike this wonderful vedio? But There is a doubt that how lateral Surface of cylinder is equal to surface area of sphere?
thanks a lot sir . love from kashmir❤
Your video is helpful for us , awesome 👍👍👍
I’m extremely appreciating you and hope all lessons are as precise as this
Thank you for your appreciating comment. Keep watching, Keep learning!

How can you said the curved surface area of cylinder equal to surface area of sphere. Give any prove
Gajab
We can say sphere of total surface area is calculated with the help of diametre. Which of the outer part as half circumference around his diametre then, how can you say that it's value you can measure in a cylinder.
sir you explained it excellently
Thank you, Chirag for that comment. Stay tuned with us for more such videos.
Thank you sir 😀😀😀
Can u plz tell why archers said that csa of cylinder = the tsa of sphere
varsha agrawal May he also not know the reason. But Archimedes proved. 😂😂😂
Thanks for explaination of sphere
Great sir
Thanks sir

Is cylinder have edge?
How can we prove that the total surface area of a sphere is 4πr^2
It was really great
Thank you so much sir
Outstanding
Where next topic volume of sphere
Wow.superb

Sir why there is pi why not 2r square
Very good sir
well explain why Archimedes said ...,
or you have only found the curved area of a cylinder
????????????????????????????????????????????????
Really good
