There are many possibilities:
A cone
A section of a sphere, and some ellipsoids, parabolids or hyperboloids
hemisphere
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.
Just one at the base, the rest is a curved surface
A cylinder perhaps
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 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.
Just one at the base, the rest is a curved surface
