Volume of prisms and spheres (8th grade math)

The volume of a sphere is 4/3πr³. We apply this formula in two word problems. The first one asks us to find how many tennis balls have a volume that exceeds one liter. The second one has to do with the volume of a pond that is 90% full of water, in shape of a half-sphere.
