A hemisphere with a radius of two has a volume of 16.8 units3
A hemisphere with a radius of 3 feet has a volume of 56.55 cubic feet.
Can not be done without the 'Given' radius and height.
The radius is 32 because the height of the hemisphere (which is half of a sphere) is the same thing as the radius (which is half the length of the diameter); the radius is the distance from the center to any point on the edge or surface of the circle/sphere.

The radius IS given, since height of hemisphere = radius of hemisphere!

Volume = about 56.55 units3
The radius of the hemisphere is 12 units.
A hemisphere with a radius of 3 has a volume of 56.55 units3

Yes its height is the same as its radius
The radius is 32 because the height of the hemisphere (which is half of a sphere) is the same thing as the radius (which is half the length of the diameter); the radius is the distance from the center to any point on the edge or surface of the circle/sphere.

Suppose the radius of the sphere is R. The base of the cone is the same as the base of the hemisphere so the radius of the base of the cone is also R. The apex of the cone is on the surface of the hemisphere above the centre of the base. That is, it is at the "North pole" position. So the height of the cone is also the radius of the sphere = R. So the ratio is 1.
