Step-by-step explanation:
Given
Hemisphere

Cone

Required
Determine the radius of the cone
First, we calculate the volume (V1) of the hemisphere.

Substitute 7 for r



Volume (V2) of a cone is:

Because the lead is cast into a cone, then they have the same volume.
So, we have:


Substitute 49 for h

Divide both sides by 49




<em>Hence, the radius of the cone is 3.74cm</em>
