1.	A cylinder , hemisphere and cone have same base and height . Find the ratio of their volume.
Answer» The height of a hemisphere is its radius. So volume of hemisphere = 2π r3/ 3 = 2π r2\xa0h/3\xa0volume of cylinder : volume of hemisphere : volume of coneπ r2h : 2π r2h/3 : π r2h /31:2/3:1/3Multiply the above ratio by 3, we get\xa03:2:1
