Cylinders, cones, and spheres are not polyhedrons, because they have curved, not flat, surfaces.A cylinder has two parallel, congruent bases that are circles. A cone has one circular base and a vertex that is not on the base.
WebThe NSW Syllabus outlines it very clearly: In geometry, the term ‘face’ refers to a flat surface with only straight edges, as in prisms and pyramids, eg. a cube has six faces. Curved surfaces, such as those found in cylinders, cones, and spheres, are not classified as ‘faces’. Similarly, flat surfaces with curved boundaries, such as the ...
