Question

A cylinder a cone a hemisphere habe same base and height find the ratio of their volume

Answer 1

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 will become radius [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

Answer 2

Answer:

the ratio of volume is 1:2:3
