What is a Cone?

• A solid or hollow geometric figure  that tapers from a circular or roughly circular base to a point.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.

What is a Sphere?

• A round geometric solid, or its surface, with every point on its surface equidistant from its center.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.
