A cone ?
Yes, it is a pyramid and a circle on the bottom
Start with a regular tetrahedron (triangular based pyramid). As you increase the number of sides in the base of the pyramid, the shape becomes more and more like a right cone. In the limit, the base tends to a polygon with an infinite number of sides - a circle, and the pyramid tends to a right cone.
a cone has a round surface and a circle bottom, but a pyramid has 5 squares. * * * * * A pyramid does not have 5 squares! It has a polygonal base with any number of sides. Attached to each of these sides, it has a triangle, and they meet at an apex.
It depends on whether or not the pyramid base remains convex or if whether some of the additional sides created ridges. If the base remains convex, sections of the pyramid base will become more like a circle and the sloped surface above that part will become smoother. It would be wrong to conclude that the pyramid would become more like a cone because it is entirely possible that all the additional sides - possibly infinitely many - are all between two adjacent vertices of the original base polygon. You would then have a base that is a segment of a circle - a third, or a quadrant, etc..
A cone ?
Flying saucer. and a cone
A circle-based pyramid, also known as a cone, has two faces: the circular base and the curved surface that tapers to a point at the apex. The base is a flat, two-dimensional shape, while the curved surface is a three-dimensional shape that extends from the base to the apex. Therefore, a circle-based pyramid has a total of two faces.
No. Polyhedra are three-dimensional objects, and the base of any prism, strictly speaking, should be two-dimensional. Any convex polygon (which is two-dimensional) can form the base of a pyramid. A circle, which is technically not a polygon, is the only convex two-dimensional figure that cannot form the base of a pyramid because it forms the base of a cone.

A pyramid (3D)! Some examples: - triangular base pyramid - square base pyramid - rectangular base pyramid - cone
The answer is "No"; a right circular cone has a circle as its base while a right triangular cone has a triangular base (which we usually call a "pyramid". The Egyptian Pyramids have square bases. And the volume of any "right" pyramid is found by multiplying the area of its base by its VERTICAL height.
