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.

Cylinder - a solid figure formed by two congruent parallel circles joined by a curved surface.
A cylinder is a geometric figure that has a round base. It consists of two parallel circular bases connected by a curved surface. Other figures with round bases include cones and spheres, but the cylinder specifically features a flat circular base.
A figure with 2 circular bases and one curved surface is called a cylinder. Examples are food cans.
A paraboloid.

You're probably thinking of a cone. There is some disagreement as to whether the point of a cone qualifies as a vertex.

"you" is not a number and so the question does not make sense.
The description given fits that of a cone.
