Question

A cone, a hemi-sphere and a cylinder stand on equal bases and have the same height. Find the ratio of their volumes as well

Answer 1

Answer:

As their base are same,

Say the radius of the base and height is R,

So, The cone’s volume: hemisphere’s Volume : Volume of cylinder.

> 1/3 x π x r^2 x r : 2/3 x π x r^2 x r : π x r^2 x r

> 1/3 x 22/7 x r^3 : 2/3 x 22/7 x r^3 : 22/7 x r^3

> 1 : 2 : 3(option B)
