Question

The ratio of radius of two right
circular cylinder
cylinder is 1:12 and the
ratio of their heights is 4:1.
Find the ratio of their volume.​

Answer 1

r = 1 , R=12 ,h=4 ,H=1

ratio = volume of cylinder/volume of second cylinder

ratio = πr^2h/πR^2H

ratio= 1^2×4/12^2×1

ratio=4/144

ratio = 1/36or 1:36
