a cone is a polyhedron
Answers
No, 'Cone' is not a 'polyhedron'.
EXPLANATION:
A ‘Cone’ is a solid that contains a circular base, curved surface and single vertex.
POLYHEDRON:
A polyhedron is the solid in “Three dimensions” with flat polygon faces, sharp corners or vertices and straight edges. The polygon faces are known as polygons, which mean that they contain straight sides.
Thus, polyhedron is bounded by straight lines and due to the curved surfaces of a cone, it is not a “polyhedron”.
No, cone is not a polyhedron.
Definition of Polyhedron
Polyhedron is nothing but the solid that is "three dimensions" with flat polygons faces and sharp vertices and straight edges. The faces of the polygon are known as "polygons" because they contain straight sides. It is known that the polyhedron is bounded by the "straight lines" and due to the "curved surfaces" of a cone.
Definition of Cone
The solid which contains a base like circle and curved surface with single vertex is called cone.
Therefore, the cone is not a polyhedron.
