Solve question no. 12
Q.12. A cone, a hemisphere and a cylinder stand on equal base and have the same height. Find the ratio of their volume.

Dear Student,
Here is the solution of your asked query:

Let r and h be the radius of base and height of the cylinder, cone and hemisphere.

We know that, Height of hemisphere = Radius of the hemisphere

h = r

Volume of cylinder = πr2h = πr2 × r = πr3

Volume of cone =  

Volume of hemisphere =

Volume of cone : Volume of hemisphere : Volume of cylinder

Thus, the ratio of their volumes is 1 : 2 : 3.

Regards
