A cone
a cone
A cone has one circular base and a vertex that is not on the base.as described on math.com
a cone that does not have a tip

Because in math the definition for vertex is !the point of a geometric figure that is opposite the base. So in this case, the point is the vertex.
The line or plane upon which a geometric figure is thought of as resting is called the base. A three-dimensional figure with a circular base and the top meeting at a vertex; it resembles a funnel cone.
The cone got its name from its shape, which resembles a geometric cone. The term originates from the Latin word "conus," derived from the Greek "kōnos," both referring to the conical form. This shape is characterized by a tapering structure that widens at the base, similar to the shape of an ice cream cone or a traffic cone. The name effectively describes the distinctive properties of this geometric figure.
You're probably thinking of a cone. There is some disagreement as to whether the point of a cone qualifies as a vertex.
An eight-sided cone is referred to as an octagonal cone. The term "octagonal" describes its base, which has eight sides, while "cone" indicates its three-dimensional shape that tapers smoothly from the base to a point (the apex). This geometric figure is not commonly encountered in standard geometry but can be understood by combining the properties of an octagon with those of a cone.
A geometric solid. The answer is NOT polyhedron. A cone, for example, which is a figure made up of the most simple geometric shapes (a straight line) and a circle, is not a polyhedron.
