Cylinder
its a lens...1 curved edge = a circle, 1 flat surface = back, 1 curved surface = front. (these are used in some battery-less flashlights, as an example.)
a giant or small cone
A sphere sliced by a plane; or a cone.
1 because all of the shape is curved except for the flat surface on the bottom
A shape with 1 vertex, 1 edge, 1 flat face, and 1 curved face is a cone. The vertex is the tip of the cone, the edge is the circular base where the flat face meets the curved surface, and the flat face is the circular base itself. The curved face extends from the base to the vertex.
The description given fits that of a cylinder.
A cone would fit the given description
A 3D shape with one curved face is a cylinder. It has a circular base and a curved surface that connects the two bases. The curved face wraps around the side, while the top and bottom faces are flat circles.
