a circle has no face
a sphere on the other hand does
The answer is - a cone.
a cylinder
flat
A "hemisphere" - a ball that's been cut into 2 equal parts. i.e "half a sphere".
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 cone. It has a circle for the base, and a curved face tapering to a point.
The answer is - a cone.
Semi Circle
2D = semi circle 3D = hemisphere
cylinder circle
It could be a semi-sphere but mostly it's a cone.
a cone
a cylinder

The shape you are describing is a cylinder. A cylinder has two circular faces, which are also known as bases, and one rectangular face, which is called the lateral face. The lateral face of a cylinder is formed by unrolling the curved surface of the cylinder into a flat shape, creating a rectangle.
