A sphere has no faces. A sphere is defined as a round symmetrical object, while a face is defined a flat surface of an object. By definition a sphere does not have any faces.
In geometry, a flat surface is also called a planar surface. The face forms a portion of the boundary of a solid geometric object. A face has edges that typically connect it to other faces. An example of a geometric object with faces is a box. A box is made up of six faces. An example of a geometrical sphere with no faces is a basketball.
