If the radius of the base of a right circular cylinder is halved, keeping the height same, what is the ratio of the volume of the reduce cylinder to that of the original.

Text Solution

Verified by Experts

Original radius=r Reduced radius=r/2 Volume of reduced cylinder/volume of cylinder cylinder `=(pir^2/4*h)/(pir^2*h)` `=1/4`.
