Question

If a hemisphere and cylinder are on equal base and have a same 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 that cone, hemisphere and cylinder have equal base and same heightThat is r = h 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
