Final answer:
A cone is not a polyhedron; it is a three-dimensional shape with a circular base and a curved surface tapering to a point.
Explanation:
A cone is a polyhedron. False. A cone is not a polyhedron. A cone is a three-dimensional geometric shape that has a circular base and a curved surface that tapers to a point, called the apex.
Unlike polyhedrons, cones do not have flat, polygonal faces. Instead, they have a curved surface that extends from the base to the apex. Therefore, the statement that a cone is a polyhedron is false.
Oftentimes, cones are likened to pyramids, but whereas pyramids have polygonal bases, cones have circular bases.
