How about globe or a sphere
A sphere.
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.
It has a flat base, a curved surface area, a circular edge and one vertex.
Such a shape probably does not have a specific name.
how many flat surfCES does a cylinder have?
a sphere has 0 flat serfaces 0 vertices
Hemisphere
A sphere is a solid figure that has 0 flat surfaces and 0 vertices. It is perfectly round and smooth, with every point on its surface equidistant from its center. Unlike polyhedra, which have flat faces and vertices, a sphere has a continuous curved surface.

A shape with 0 vertices and 2 flat surfaces is a cylinder. The two flat surfaces are the circular bases at the top and bottom, while the curved surface connecting them does not count as a flat surface. Other than the cylinder, a shape that fits this description is a circular disk, which also has no vertices and one flat surface, but when considering the top and bottom of the cylinder, it effectively has two flat surfaces.
The solid figure that has 2 flat surfaces and 0 vertices is a cylinder. A cylinder consists of two parallel circular bases (the flat surfaces) connected by a curved surface. The bases do not have any vertices, as they are continuous curves.

Technically, there's no shape with no surface and no vertices, but a sphere is close. It has no vertices but has just one surface.
0 vertices 0edges 2 flat surfaces
A ball, which is a three-dimensional object, is considered a sphere in geometric terms. It has no edges or vertices, as it is a perfectly smooth surface without any flat faces. Therefore, a sphere has 0 faces, 0 edges, and 0 vertices.
