There are many possibilities:
A cone
A section of a sphere, and some ellipsoids, parabolids or hyperboloids
hemisphere
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 cone has one flat surface, which is its circular base. The curved surface that extends from the base to the apex is not flat. Therefore, in total, a cone has one flat surface.
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 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.
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.
hemisphere
A cone.
A sphere sliced by a plane; or a cone.
a giant or small cone
It has a flat base, a curved surface area, a circular edge and one vertex.
"you" is not a number and so the question does not make sense.
The description given fits that of a cone.
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.
A cylinder has 2 equal parallel flat surface circular bases and a curved surface body.
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
