A curved surface figure is a three-dimensional shape that has at least one curved surface, rather than just flat faces. Examples include spheres, cylinders, cones, and toroids. These figures can vary in complexity and can exhibit various properties related to their curvature, such as volume and surface area. Unlike polyhedra, which are made up of flat polygonal faces, curved surface figures often have smooth, continuous surfaces.
Cylinder - a solid figure formed by two congruent parallel circles joined by a curved surface.

The solid figure you're describing is a cylinder. It has two circular bases, but if we consider a cylinder without its bases, it consists of a single curved surface wrapping around the height of the cylinder. Another example of a solid figure with one curved surface and no bases is a cone if we only consider the curved part without the base.
