Because the literal meaning of polyhedron means 'many faces' A sphere has only one face.
A polyhedron can have any number of faces 4 or higher.

Tetrahedron
A sphere is not a polyhedron because it has no edges, no vertices and no flat faces The word 'polyhedron' means many faces.
A non polyhedron with 0 bases is a sphere.
No, a sphere is not a polyhedron.A polyhedron is a three-dimensional geometric figure whose sides are polygons.A regular polyhedron is a polyhedron whose faces are all congruent regular polygons.
no its a sphere
A sphere is a geometric solid because it has 3 dimentions.
NO a cone is not a polyhedron as it has a curved surface. Similarly sphere and cylinders r 3D but not polyhedrons
No. By definition a polyhedron has to have faces (flat surfaces), edges, and vertices. A sphere, hemisphere, and a cylinder are all solids but are not polyhedra.
It is called a face of the polyhedron.
A polyhedron has "many sides" (by definiton). The only 3-D shape which does not have "many sides" is a sphere (which technically only have one "side").
It is a truncated icosahedron projected onto a sphere.
It is a face of the polyhedron
They are the faces of the polyhedron.
