Which has a greater effect on the volume? changing the radius by a given amount or changing the height by the same amount?

doubling the radius will have a greater effect

v of cylinder=pi x square of radius x hieght

lets take an example,r=2,h=2

v=8pi

doubling the hieght,h=4

v=16pi ie twice the initial volume

doubling the radius,r=4

v=pi x 16 x 2

=32 pi ie four times the initial volume

therefore radius makes a bigger difference

Changing the radius by a given amount has a greater effect on the volume than changing the height by the same amount. This is because the value of the radius is squared in the formula.
