Answer :

Given, a cone, a hemisphere and a cylinder stand on equal bases and have the same height
Given, radius of cone = radius of hemisphere = radius of cylinder = r
Height of cone = height of hemisphere = height of cylinder = h
Volume of cone = 1/3 πr²h
Volume of hemisphere = 2/3 πr³
Volume of cylinder = πr²h
Ratio of volume = 1/3 πr²h : 2/3 πr³ : πr²h
= 1/3 : 2/3 : 1
= 1 : 2 : 3
