Volume of cone = (1/3)πr2h
Volume of hemisphere = (2/3)πr3
Volume of cylinder = πr2h
Given :-
The cone, hemisphere and cylinder have equal base and same height
so, the height = [r]
Then,
Volume of cone : Volume of hemisphere : Volume of cylinder
=(1/3)πr²h : (2/3)πr³ : πr²h
= (1/3)πr³ : (2/3)πr³ : πr³
= (1/3) : (2/3) : 1
= 1: 2: 3
