Answer:
No, a cone is not a polyhedron.
Step-by-step explanation:
A solid having flat faces is called Polyhedrons,
In other words, a solid with no curved side is called Polyhedrons,
Example : Cube, prism or pyramid etc...
Also, each faces of the polyhedron is a polygon,
Now, a cone is a solid that has a circular base joined to point by a curved side.
But by the above definition,
There is no curved side in a polyhedron,
Therefore, cone is not an example of polyhedron.
