A solid hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface forms the outer part of the hemisphere, while the flat base is the circular face at the bottom.
A cylinder or a cone. Or a hemisphere.
A solid that has only curved surfaces is a cylinder or a sphere. However, the sphere is the most common example of a solid with exclusively curved surfaces, as it is perfectly round and has no flat faces. In contrast, a cylinder has two flat circular bases in addition to its curved surface.

It is a cylinder
One if it is solid, two if it is hollow

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 solid with a curved surface is a sphere. Spheres are three-dimensional shapes where every point on the surface is equidistant from the center. Other examples of solids with curved surfaces include cylinders and cones, which have curved sides but flat bases. These shapes differ in their properties and dimensions but share the characteristic of having curves in their surfaces.
