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 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
