I WONDER - What Is A Cylinder?

The video tutorial explains the properties of a cylinder, highlighting its curved edges and parallel faces. It contrasts these features with other 3D shapes like cubes, prisms, and pyramids, which have straight edges. The tutorial also mentions cones, which have curved edges, and spheres, which have no edges.

Can you name another 3D shape that has curved edges?

What is unique about a sphere in terms of edges?
