Yes, it is a pyramid and a circle on the bottom
Wouldn't a circle-based pyramid look a lot like a cone ? If so, you could probably use the formula for the volume of a cone and get away with it.

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.
Radius is the name for half the diameter of a circle. A pyramid is not associated with a circle therefore it cannot have a radius. The closest shape would be a cone.

A pyramid with a circle as it's base is also called a cone and it has two faces.

Flying saucer. and a cone
maybe
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.
Radius is the name for half the diameter of a circle. A pyramid is not associated with a circle therefore it cannot have a radius. The closest shape would be a 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.
