The description given fits that of a cone.
The description given fits that of a 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.
It's a rectangle.
The solid figure you're describing is a cylinder. It has two circular bases, but if we consider a cylinder without its bases, it consists of a single curved surface wrapping around the height of the cylinder. Another example of a solid figure with one curved surface and no bases is a cone if we only consider the curved part without the base.
