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 cone
Cone
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.
sphere
cylinder?
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
Hemisphere
A solid figure with 2 flat surfaces and 0 vertices is a cylinder. A cylinder has two circular flat surfaces, known as bases, and no vertices because it does not have any corners or points where edges meet. It is a three-dimensional shape that is formed by a curved surface connecting the two bases.
none!all shapes are flat
