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 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 circle?
A cone has only one vertex and a circular base
A Sphere only has one face and no verticies.
It sounds like the shape of a sphere
A cone has only one edge simply because it only has one face. Although one face may have several edges, a circle is a closed figure with only one vertice, resulting in one edge. The rest of the shape is 3-D, but with only one face, there is an infinite amount of points on a cone. The cone joins on another vertice, but since the face is a circle, there is still only one actual edge. Thus, there is only one edge on a cone because there is a single, circular face.
