If you consider a cylinder, it has two faces, of you consider a cone instead, it has one face ONLY.
A cone and a cylinder are two of them
A solid that has only curved surfaces is a cylinder or a sphere. However, the sphere is the most common example of a solid with exclusively curved surfaces, as it is perfectly round and has no flat faces. In contrast, a cylinder has two flat circular bases in addition to its curved surface.
A sphere
A cylinder has 2 opposite parallel flat surfaces.
The shape is called sector. The formal mathematical definition of sector is the portion of a circle bounded by two radii and the included arc.

A sphere is the shape of a ball, and a cylinder is like a tin can; rounded at the middle but with two flat surfaces at the top and bottom.

a sphere, of course!
A SPHERE has no vertices and no FLAT surfaces
