a sphere/ball or neither. it may be nothing
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. A hemisphere.
Just one at the base, the rest is a curved surface
A paraboloid.
a sphere
A sphere has one surface that's also curved and has no base.
