One possible answer is an infinite cone. Spheres have one face but no vertex. No physical 3-D shape can have a vertex without having more than one face (a real cone typically has two: side and bottom).
cylinder
A sphere intersected by a plane, An circular ellipsoid intersected by a plane, A cylinder, A cone, and many more shapes, some of which don't even have a name!
A cylinder and a cone have infinitely many planes of symmetry because of the circular face. However, a cylinder can also be cut in half lengthwise (imaging cutting a soda can in half), while a cone cannot (imagine cutting a ice cream cone in half). Therefore, a cylinder has one more plane of symmetry than a cone.
Mathematically, the shape is known as a toroid. More prosaically, it is a circular disk with a smaller circular disk removed from its centre.
The apical angle of a cone is the angle formed at the apex (or tip) between the two sloping sides of the cone. It is also known as the vertex angle. The value of the apical angle determines the shape of the cone - a smaller apical angle will result in a more acute cone, while a larger apical angle will produce a more obtuse cone.
Im here to answer your question- possibly a cone. * * * * * and give you the wrong answer. A cone is a shape with 1 vertex: not MORE THAN 1 vertex! All polyhedra have more than 1 vertices.
it breaks down
A picture that looks like the shape of a cone not describe an MDC or more developed country. A cone or pyramid shape would show a LDC or lower developed country.
Deimos is more circular than Phobos. Deimos has a nearly circular shape with an eccentricity of only 0.00033, while Phobos is more elongated with an eccentricity of about 0.0151.

The track forecast cone represents the uncertainty in the path a hurricane will take. The more days in advance you try to predict a hurricane, the less certain you are about where it will be. The result is a cone shape.
