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

sry but u r wrong.... last they are asking curved surface area .... so this answer is absolutely incorrect
okay, I misread it. I will re-do okay?
no no koi nhi u give yr best..... appreciating... but nw the gt the right answer
i don't understand what you said. can you tell me again ?
I mean it's OK..... u give your best..... but nw i gt the correct answer
cone = pi *rl
cylinder = 2 pi rh
hemisphere = 2 pi r^2
ratio will be
pi rl : 2pi r h : 2pir^2pi,
l : 2h :2r
so sorry for the mistake the first time
cylinder = 2 pi rh

answer is 2: root2 : 2
