Examples of non polyhedron are cone cylinder spere
(if the question is: which of the following are polyhedrons?) your answer is: pyramid and prism ( apex )
A cylinder would fit the given description
No, a prism has flat sides. Triangular prisms are very common, but any polygon can be the cross section of a prism.
A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
No, it cannot.
No, it is not.
No. A polyhedron has plane faces; a cylinder has one curved face.
No. Nor is a cylinder!
false
Yes.
Examples of non polyhedron are cone cylinder spere
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.
A cylinder.
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.
