Question

a sphere and a hemisphere have same radius. what is the ratio of volume of thr sphere to volume of the hemisphere​

Answer 1

Since the cone and the hemisphere have the same base their radii are equal. We will take it as r units.

Let the height of the cone be h. The hemisphere is of height = radius r.

Given volume of the cone = volume of the hemisphere.

So (1/3) π r^2 h = (2/3) πr^3

Simplifying h = 2r or h:r = 2:1

Ratio of the heights of the cone and hemisphere = 2:1.
