A polyhedron is a 3 dimensional figure made of polygons. A cylinder is made of two circles and a rectangle around the middle. Since circles are not considered polygons (don't have straight edges), a cylinder cannot be a polyhedron. I just had a discussion about this with my math students today.

Is a cylinder a polyhedron and if not Why not?
The simple answer is no, because it has a curved surface. A polyhedron is made up of polygons. The curved portion of a cylinder is not a polygon. The circular faces are not polygons either, as they do not have at least 3 sides. This information provided by my 11 yr old Son. He's pretty smart.
Is a rectangle a polyhedron?
yes it is a polyhedron
Is a cuboid a polyhedron?
no a cuboid is not a polyhedron if it was it would have 9 faces
Why decahedron is not a regular polyhedron?
It is not a regular polyhedron because it has unequal sides
What is the formula for volume of a polyhedron?
There are different formulae for different polyhedra and these depend on what information about the polyhedron is given.
Is a cylinder a polyhedron?
No, it is not.
A cylinder is a polyhedron?
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
Is a hexagonal cylinder a polyhedron?
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
Can a cylinder be a polyhedron?
No, it cannot.
Is a cylinder a regular polyhedron?
No, it is not.
Is a cylender a polyhedron?
No. A polyhedron has plane faces; a cylinder has one curved face.
Is a cilindar a polyhedron?
No. Nor is a cylinder!
A cylinder is a polyhedron with circular bases.?
false
Is a hexagonal shaped cylinder a polyhedron?
Yes.
Can you gave any examples of non-polyhedron?
Examples of non polyhedron are cone cylinder spere
This shape is not a polyhedron it is a prism two of its faces are circles?
A cylinder.
Is every polyhedron a solid?
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.
