Question

If a cone a hemisphere and a cylinder are on equal bases and their height is also equal. Find the ratio of their volumes.

Answer 1

Answer:

Let radius of their base is r

Their height is h

Since their height and radius are equal ,so

Vol. Of cone=1/3*22/7*r*2h

Vol. Ofcylinder=22/7r*2h

Vol of hemisphere=2/3*22/7*r*3

Ratio=1/3rh:rh:2/3
