31. Special 3-D Shapes Cylinder Sphere Cone

32. Sphere Every point on the surface of the sphere is the same distance from the center The normal definitions of faces, edges and vertices are not appropriate for a sphere.

33. Cone The point of the cone is directly above the centre of the circular base. The normal definitions of faces, corners and edges are not appropriate for a cone.

34. Cylinder A prism with a circular cross- section. The normal definitions of faces, edges and vertices are not appropriate for a cylinder.
