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.
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
Ur teaching technique is good... amazing
Hey Priyanka,
Thankyou so much for appreciating our work.
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
It was really helpful. Thank you very much!!!😊
Happy to know that our videos were helpful to you.

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
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?
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
Made me understand better.
Thank u👍😀😀
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.
Thank you so much for such a concise explanation. Very much appreciated.

Hii
Md Mohsin Ansari Gregg murder
@@tamizuddinansari7609 huh?
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...
Thanks for explaining the surface area of a sphere
Hello Thankyou For your Feedback Check out more videos on our channel ua-cam.com/users/Letstute
thanks a lot sir . love from kashmir❤
thanks for the wonderful explanation sir.
Mind blowing
Jordar
It will help students to easy learning
Keep it up
Thank you for your appreciating comment. Keep watching Keep learning!
Sir, please tell how lateral surface area of sphere is equal to surface area of sphere
Please answer
It's really really good explanation of 3d structure..😁😁😁🥰
Cool, thanks for that!
Superb sir,, very easy way ....thanx..
Thank you for your appreciating comment. Keep watching, Keep learning!
Vrry helpful video sir thank you very much for this sir
Hey, you are welcome! we are always happy to help you. There are many more Math videos on our channel please do check them out.
What a nice explanation really I could understand a lot from the video than the school teaching
I wish that if i could talk and see you, or else if I could give you grand slam due to the mystery made easier by you.
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
Your video is helpful for us , awesome 👍👍👍
Aag la dala
I’m extremely appreciating you and hope all lessons are as precise as this
Thank you for your appreciating comment. Keep watching, Keep learning!

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.
Thank u it saved my time👌😄
Thank you sir 😀😀😀
Thq so much for clearing my doubt
sir you explained it excellently

Thanks for explaination of sphere
Great sir
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 like you accent its funny and relaxing

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.
Your explanation is much better
Thank you for your comment. Please do try them. Good luck!
Nice! Covered cool content.
How can you said the curved surface area of cylinder equal to surface area of sphere. Give any prove
Very nice explanation

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. 😂😂😂
Tq so much
Thanks it helped me
Happy to Know that the videos was helpful to you
nice explanation.
Thanku For Your valuable comment
showing Archimedes prove would be great.
Very good sir

Where next topic volume of sphere
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.......???
Thank
