A cone and a cylinder are two of them
Cylinder
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.
Three-dimensional figures with a curved surface are not considered polyhedrons because polyhedrons are defined as solids with flat polygonal faces, straight edges, and vertices. Curved surfaces lack these flat faces and straight edges, which are essential characteristics of polyhedrons. Examples of shapes with curved surfaces include spheres and cylinders, which do not fit the definition of a polyhedron. Thus, the presence of curved surfaces distinguishes these figures from polyhedra.
A solid cylinder has three plane surfaces: two circular bases at the top and bottom, and one curved lateral surface that wraps around the sides. The curved surface is not a plane surface, while the two bases are. Thus, there are two plane surfaces in a solid cylinder.

A solid cylinder has three plane surfaces: two circular bases at the top and bottom, and one curved lateral surface that wraps around the sides. The curved surface is not a plane surface, while the two bases are. Thus, there are two plane surfaces in a solid cylinder.
two figures that make a regular rectangle * * * * * Not so. There is no such thing as a regular rectangle. If there were one, it would be a square and not a rectangle. Furthermore, faces are associated with solid (3-dimensional) objects, not plane figures. A face is any one of the 2-dimensional plane boundaries or surfaces of a solid object. Sometimes the term is also used for curved surfaces.
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.
