Question

A cone, A hemisphere and a cylinder stand on equal bases and have the same height show that their volumes are in the ratio 1:2:3
Please answer it as soon as possible

Answer 1

Volume of cone = (1/3)πr2hVolume of hemisphere = (2/3)πr3  Volume of cylinder = πr2h Given that cone, hemisphere and cylinder have equal base and same height That 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
