Question 923852
If the radius of the cylinder is halved,find the ratio of the volume of the new cylinder formed to its orginal one, assuming that the height remains unchanged?
-----
Original Volume:: V = pi*r^2*h
-----
Modified Volume::
V' = pi(r/2)^2*h
---
V' = (1/4)pi*r^2*h
-----
Ratio of new to original:: V'/V = (1/4)pir^2h/(pir^2h) = 1/4 = 1:4
