    Question is still remains same that why lateral surface area of cylinder is equal to surface area of sphere.

    • @hlooo950
      @hlooo950 3 роки тому +5

      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😊

    @RickyRoro777 8 років тому +14

    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.

    Sir if surface area of sphere will not be equal to the lateral surface area then what will be the surface area of sphere??

    • @Letstute
      @Letstute  6 років тому +1

      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.

    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.
