Cones do but pyramids don't
no because it has curved faces.
A polyhedron is defined as a "geometric solid in three dimensions with flat edges and straight faces". As both cylinders and cones have curved faces, neither are polyhedra.
The description given fits that of cones
A cone has two faces: one around (the curved part), and one on the flat base. It has one vertex at the point at the top and one edge where the curved section meets the flat base.
It has no CURVED faces.
it has 0 curved faces
Cones have curved lateral surface, pyramids don't.
"Dose" is a measured portion of a medicine. I am not aware of any cones that have measured quantities of medication! A cone has two faces - a circular face at its base as well as a curved face.
Pyramids, no; cones, yes (except the base).
It has 8 curved faces
It has no CURVED faces.
A rectangular prism is a cuboid. It has no curved faces.
