a cylinder
cone
The answer is a cone
The solid figure you are describing is a prism. A prism has two congruent polygonal bases that are parallel and connected by rectangular lateral faces. The shape of the prism is determined by the type of polygon used for the bases, such as a triangular prism or a rectangular prism. Each lateral face is a rectangle that connects corresponding sides of the two bases.
A cone
It the circular face is uniform along it's length then the shape is a cylinder.
A rectangular pyramid.
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
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.
A rectangular pyramid. Did that answer your question? ;)
