A cone
The base of a cylinder is the circular part. What exactly are you trying to DO with it?
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 cone has one circular base and a vertex that is not on the base.as described on math.com

A right circular cone is perfectly balanced on its circular base. Imagine a cone that has a circular base, but leans to one side - this is a non right circular cone.

A Right Circular Cone is one wherein the base of the cone is circular and the axis of the cone is perpendicular to the base and passes through the center of the base and the vertex of the cone.
