It has one flat face if its 2 dimensional. It has 6 flat faces if it is 3 dimensional.
The answer is - a cone.
A Cone
A cone.
face
A square-based pyramid has five flat surfaces: one square base and four triangular faces that converge at the apex. The base is the square, while each of the four sides of the square forms a triangular face with the apex.
Just the one square flat face.

A hemisphere
A face.
It has 5 flat faces because there are 4 flat faces at the top and 1 flat face at the bottom.
The solid that has one flat face, one curved face, one edge, and one vertex is a cone. The flat face is the circular base, the curved face is the conical surface, the edge is the circular boundary where the base meets the curved surface, and the vertex is the pointed tip of the cone.
It could be a semi-sphere but mostly it's a cone.
The object described is a cone. A cone has one vertex (the point where the flat face meets the curved surface) and one flat face (the circular base). Due to its shape, a cone can roll along a flat surface smoothly.
