No, it is not.
No, a cylinder cannot be accurately represented on a polyhedron poster because a cylinder is not a polyhedron. While both a cylinder and a polyhedron may have congruent bases, a polyhedron is defined by its flat polygonal faces, while a cylinder has curved surfaces. Therefore, including a cylinder would misrepresent the characteristics that define polyhedra.
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.

No, it cannot.
No. A polyhedron has plane faces; a cylinder has one curved face.
No, it is not.
It is not a regular polyhedron because it has unequal sides

No, it cannot.
No. It is a semi-regular polyhedron. Explanation. The truncated icosahedron is a polyhedron that can be constructed from an icosahedron with the 12 vertices truncated (cut off) such that one third of each edge is cut off at each of both ends. This creates 12 new pentagon faces, and leaves the original 20 triangle faces as regular hexagons A regular polyhedron is a polyhedron whose faces are congruent regular polygons. The truncated icosahedron is NOT a regular polyhedron, it is a semiregular polyhedron. It is a uniform polyhedron.
No. A polyhedron has plane faces; a cylinder has one curved face.
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. Nor is a cylinder!
The sides of a rectangle are not all equal so a rectangle is not a regular polygon. And, as a consequence, any 3-dimensional shape made from rectangles cannot be a regular polyhedron.
No.
No. A polyhedron is 3 dimensional. You have a regular polygon, regular because the sides are equal. If you asked about 20 surfaces, then it would be a polyhedron.
