Question

A cylinder,cone and hemisphere have some bases same height find the ratioof their volume

Answer 1

Answer:

Given a cylinder, a cone and hemisphere have same bases and same height.

radius of cylinder=radius of base of cone =radius of hemisphere= r

height of cylinder=height of cone=height of hemisphere=h

volume of cylinder=πr^2h

volume of cone=πr^2h/3

volume of hemisphere=2/3 πr^2×r=2/3 πr^2×h=2/3 πr^2h

ratio of volume of cylinder: volume of cone : volume of hemisphere=3:1:2
