i dont know i think its a circular prism or something else

No it is not. Because a prism has two plane faces - at opposite ends.
It could be an ellipsoid or spheroid sliced by a plane (a hemisphere, for example). Or a torus sliced by a plane (top half of a doughnut). Or a cone.
A cone.
A cone would fit the given description
A cylinder. Technically, the curved surface of a cylinder is not called a face, only the flat surfaces, so a cylinder has 2 faces and one curved surface.
sphere
half a sphere

Cylindrical shape or Cylinder shape
One curved surface (that goes round the cylinder) and 2 flat ends
A Semi-Sphere :)
a sphere
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.
