Question

if base radius of a right circular cylinder is halved and the height cm find the ratio of the volume of cylinder to that of the original cylinder ​

Answer 1

Answer: 1:4

Step-by-step explanation:

volume of original cylinder = pie*(r)^2*h

new r = r/2

new volume = pie*(r/2)^2*h

                   = pie*(r)^2*h/4

ratio of new volume to original volume = 1/4

                                                             = 1:4
