sphere has 1 face and no vertex and it rolls but cone has 2 faces and it can roll and it has 1 vertex
cone
NO a cone is not a polyhedron as it has a curved surface. Similarly sphere and cylinders r 3D but not polyhedrons
The ratio is given as the sphere volume divided by the volume of the cone. The volume of a sphere that satisfies these conditions is 4/3 x pi x r cubed, and the volume for the cone is 2/3 x pi x r cubed, where r is the radius and pi is equal to 3.14. Dividing these two volumes, you find the resulting ratio is 2.
A pyramid have at least one vertices's and a cone have none because no edges meet on the cone at the top because cones only have 1 edge

Actually seeing the relationship between the volumes of a cone (one-third of a cylinder) and a sphere (two-thirds of a cylinder) is hard to beat. The cylinder is 1/3 the volume of the cone

The ancient Greek mathematician Archimedes proved that the volume of a sphere is four times that of the cone with base equal to a great circle of the sphere and height the radius of the sphere. Maybe this is what the poser of the question meant.
They are all 3D geometric shapes.
No, it is not.
A hemisphere is half a sphere
Sphere is whole a hemisphere is not
the difference between a cone and a prism is that a cone has no edges and only one vertex and a prism has both edges and vertexes.
cone
The cone has one. Neither the cylinder nor the sphere has any.
