Question

If the diameter of cylinder is interested by 20%then how much height will decrease to maintain same volume ..

Answer 1

$\huge{bold{Answer :}}$ According to formula of cylinder ( Volume) = π r^2h
If we increase it's diameter = 20%

radius = 2* 20% = 40%
Now.,
Volume of cylinder = π ( r + 40%)^2 * h
For same volume..
