sphere
A triangle with a circular base
A cylinder has a circular face at each end, and a rectangular face folder around the middle. The only edges are the edges of the circular ends.
There is no shape which has only circular faces.
The top view of a cone is a circular shape, representing the base of the cone as seen from directly above. In this view, the apex of the cone is not visible, and only the circular outline of the base is displayed. The radius of the circle corresponds to the radius of the cone's base.
The base of a square pyramid is the only face that is a square - all the others are triangular in shape. So you do not need any measurements to determine which is the base.
Its a sphere.
The shape you are describing is a cylinder. A cylinder has two circular faces, which are also known as bases, and one rectangular face, which is called the lateral face. The lateral face of a cylinder is formed by unrolling the curved surface of the cylinder into a flat shape, creating a rectangle.
A cone has one circular face. It only has one vertice and it does not have any edges since the face is circular.

A cone is a three-dimensional shape. It has a circular base and tapers smoothly to a point called the apex. This shape occupies space and has depth, height, and width, distinguishing it from two-dimensional shapes, which only have length and width.
A cone has only one vertex and a circular base
A Sphere only has one face and no verticies.
