Answer:
Let the base radii of them be r and height h.
Then ratio of volumes
cone : hemisphere : cylinder
=31πr2h:32πr3:πr2h [but h = r]
=31πr2r:32πr3:πr2r
=31πr3:32πr3:πr3
=31:32:1
=1:2:3

Answer:
Let the base radii of them be r and
height h.
Then ratio of volumes
cone hemisphere : cylinder
=31mr2h:32mr3:mr2h [but h=r]
=31mr2r:32m3:πr2r
=31m3:32T3:3
= 31:32:1
=1:2:3
