Question

If the radius of a cylinder is doubled and the height is kept same, then how the volume will

change? What will be volume when the height is halved?​

Answer 1

Answer:

Volume = area of cross section * height

Volume is directly proportional to square of radius and linearly with height.

Also V = πR²H

If radius is doubled then the volume will be 4 times the original volume.

If height is halved then volume will be half times the original volume.
