Cylinders polyhedron

WebPolyhedrons are space figures with flat surfaces, called faces, which are made of polygons. Prisms and pyramids are examples of polyhedrons. Cylinders, cones, and spheres are not polyhedrons, because they have curved, not flat, surfaces. A cylinder has two parallel, congruent bases that are circles. http://www.math.com/school/subject3/lessons/S3U4L4GL.html

Why are cylinders spheres and cones not polyhedrons?

Webaxis is perpendicular to the bases, then the cylinder is a right cylinder. If the axis is not perpendicular to the bases, then the cylinder is an oblique cylinder.
