Cylinder
A prism has no curved surfaces. It has 5 or more flat faces.
A hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface is the rounded part of the hemisphere, while the flat base is the circular face that lies on the ground or surface.
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.

Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.

a cone.
2 flat and 1 curved
An empty cone (like an ice-cream cone) doesn't have any flat surfaces. It has two curved surfaces, one outside and one inside. A solid cone has a flat base, and one other curved surface.
