a cone
A solid figure with one circular base and one curved surface is called a cylinder. In a cylinder, the circular base is parallel to the other circular base (if there is one), and the curved surface connects the edges of the base, forming a three-dimensional shape. If it has only one base, it can be considered a cone, which has a circular base and a single curved surface that narrows to a point.

A cylinder. (This isn't a fake answer.)
Cone
A solid figure with one circular base and one curved surface is called a cone. It tapers smoothly from the circular base to a single point known as the apex or vertex. The curved surface connects the base to the apex, creating a three-dimensional shape commonly found in various real-world objects, such as ice cream cones and traffic cones.
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 solid hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface is the outer part of the hemisphere, while the flat base is the circular section that sits on a plane.
The solid shape you are describing is called a cone. A cone has a circular base and narrows to a single vertex, or apex, at the top. Its curved surface connects the base to the vertex, distinguishing it from other solid shapes.
A paraboloid.
A cone would fit the given description.
A three-dimensional figure with one vertex and one circular base is called a cone. The circular base is located at the bottom, while the vertex, or apex, is the point at the top where the sides converge. Cones can vary in size and can be right or oblique, depending on the alignment of the apex with the center of the base.
