A cone would fit the given description
There cannot be such a shape. It is not a cylinder because a cylinder sdoes not have a rectangular face. A rectangle must be a flat face and the only flat faces in a cylinder are the circle faces. The curved face can be "opened out" into a rectangular shape but because the face is curved it cannot be rectangular.

A cylinder
A sphere sliced by a plane; or a cone.
curved
A shape with 1 vertex, 1 edge, 1 flat face, and 1 curved face is a cone. The vertex is the tip of the cone, the edge is the circular base where the flat face meets the curved surface, and the flat face is the circular base itself. The curved face extends from the base to the vertex.
A 3D shape with one curved face is a cylinder. It has a circular base and a curved surface that connects the two bases. The curved face wraps around the side, while the top and bottom faces are flat circles.
The shape you are describing is a cylinder. A cylinder has two flat circular faces (the top and bottom) and one curved surface that wraps around the sides. It has no edges or vertices where flat surfaces meet, as the curved surface is continuous.

The answer is - a cone.
A Cone
A cone. It has a circle for the base, and a curved face tapering to a point.
