It is a sphere which looks like a globe
A semicircle
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.
A sphere would fit the given description
A solid figure with one circular base and one curved surface is called a cylinder. In a cylinder, the circular base is parallel to the other circular base (if there is one), and the curved surface connects the edges of the base, forming a three-dimensional shape. If it has only one base, it can be considered a cone, which has a circular base and a single curved surface that narrows to a point.
a sphere has no bases and it only has one curved surface

I am not sure that such a surface can exist.
Spheres and spheroids have.Wait ! Don't go away. Any solid of revolution generated bya plane figure with only curves will have only a curved surface.

Because that is how a polyhedron is defined.
The tetrahedron has only four faces. A sphere has only one, but that's probably not what you meant since the surface of a sphere is curved.
