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😊
Really it was an awesome video,👏👏 easy to understand the concepts of sphere👍 keep it up 👌
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 🤔🤔🤔
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.
Ur teaching technique is good... amazing
Hey Priyanka,
Thankyou so much for appreciating our work.
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

I love you man, your voice, the way you make us understand!! Love you love you love you! Thanks a bunch😘😘😘
we can make all sizes stainless steel sphere . www.stainless-steel-sphere.com
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?
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
It was really helpful. Thank you very much!!!😊
Happy to know that our videos were helpful to you.

thanks a lot sir . love from kashmir❤
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.
Mind blowing

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 explaining the surface area of a sphere
Hello Thankyou For your Feedback Check out more videos on our channel ruclips.net/user/Letstute
thanks for the wonderful explanation sir.
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...
It's really really good explanation of 3d structure..😁😁😁🥰
Sir, please tell how lateral surface area of sphere is equal to surface area of sphere
Please answer
Made me understand better.
Thank u👍😀😀
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.

I was under this challenge since many days but it is completely solve with your visionory video.
Love and regards for your wonderful methid of teaching
really excellent. ..understood undoubtedly. ..
hey pragati that's very good to know. watch our other sessions on maths and statistics

Very helpful and easy to understand
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.
Thq so much for clearing my doubt
Best one.good job

Nice! Covered cool content.
Great sir
Thanks for explaination of sphere
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?
Very good indeed mister
Thanks sir

How can you said the curved surface area of cylinder equal to surface area of sphere. Give any prove
nice explanation.
Thanku For Your valuable comment
csa/lsa ?
👍👍👍
Thank you for that comment.
Helpful vid
Thank You, Your comments is valuable for us
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. 😂😂😂

Is there any proof of the law of arcemedis?
Also show that surface area of sphere is equal to the lateral surface area of cylinder of same radius
Hi
Tq so much
Outstanding
Wow.superb
Thank you so much sir
Really good
Very helpful

❤❤❤❤❤
Is cylinder have edge?
Find the area of fourth part of a sphere with radius r
Why lateral surface area of hemisphere is equal to half of cirle total surface area ,2pie r²
😊
पर L. S. A. Of cylinder का formula तो 2*पायी *r*h होता है bt आपने बताया है that formula of L. S. A. Is equal to T. S. A Of sphere & u say formula is 4*paayi*r*square.......???
Awsome
Nic way of explaining.

Thank you for suggesting that topic.
well explain why Archimedes said ...,
or you have only found the curved area of a cylinder
????????????????????????????????????????????????
Oooh aaa ex de v 4 times area of cirle equal aaa shpere de area de guve example de
Nice
Thank you
