A cone ?
A cone
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..
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 is a pyramid in its limit - when the base has infinitely many vertices.
Yes, it is a pyramid and a circle on the bottom
A cone
A pyramid with a circle as it's base is also called a cone and it has two faces.

The Narcotics Anonymous symbol is a circle with a square standing on it's corner within the circle. (The square looks like a diamond shape like a baseball field - consider home plate at the bottom of the circle, 2nd base at the top of the circle, and 3rd and 1st base on the left and right sides of the circle, respectively.) Each of the corners of the square are touching the circle. Each area has meaning. The outer circle symbolizes a universal and total program with room for all that comes from being in recovery. When you look at the symbol as one dimensional the square looks like just that, a square. If you look at the symbol as three dimensional you can now imagine the square as the base of a pyramid. The square base of this pyramid is Good will. This is not only the base of the pyramid, but also the base of Narcotics Anonymous and the recovering addict. Good will is best shown in service when addicts do the right thing for the right reason. The four pyramid sides that rise from the base of the square represent Self, Society, Service, and God. The imaginary sides of the square that rise up to form a pyramid come to a point, which is Freedom.

A cone is a common pyramid-like figure where the base is a circle or other closed curve instead of a polygon. A cone has a curved lateral surface instead of several triangular faces, but in terms of volume, a cone and a pyramid are just alike.
The circle.
A cone is a pyramid in its limit - when the base has infinitely many vertices.
The heart is shaped somewhat like a pyramid. The left ventricle, at the "bottom" is the apex, and the "top" is more like the base of the pyramid (even though it is a rather inverted pyramid).
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.
