Why is a cylinder not a polyhedron?

A polyhedron is a 3 dimensional figure made of polygons. A cylinder is made of two circles and a rectangle around the middle. Since circles are not considered polygons (don't have straight edges), a cylinder cannot be a polyhedron. I just had a discussion about this with my math students today.
