The radius of a sphere is p units and the radius of a hemisphere is 2p units. What is the ratio of the volume of the sphere to the volume of the hemisphere?
Hemisphere volume = (1/2)(4/3) pi * p^3 = (2/3)pi* p^3
Sphere volume = (4/3) pi * (2p)^3 = (4/3)pi * 8p^3 = (32/3)pi p^3
Sphere Volume (32/3) pi * p^3 (32/3) 32
_________________ = _____________ = _______ = ___ = 16
Hemisphere Volume (2/3) pi * p^3 (2/3) 2
