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.
A cone could be a party hat && a sphere couldd be a bowling ball.
cone
maybe
For example, a sphere or an ellipsoid.
A sphere to a cone is the same as a circle is to a triangle but they are both 3 dimensional.
None, unless there is a relation between the semicircle and the cone that you have chosen not to share.
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
sphere has 1 face and no vertex and it rolls but cone has 2 faces and it can roll and it has 1 vertex
They are all 3D geometric shapes.
No, it is not.
cone
The cone has one. Neither the cylinder nor the sphere has any.
Sphere
A cone could be a party hat && a sphere couldd be a bowling ball.
No a sphere is a solid with no vortexes, faces, or edges while a cone has two faces, one vortex, and one edge.
A cone sphere, often referred to in geometry, is a three-dimensional shape that combines features of both a cone and a sphere. It generally describes a solid where a cone is placed on top of a sphere, sharing a common base. This hybrid shape can be examined in various mathematical contexts, such as in calculating volume or surface area, and is often used in design and architecture for aesthetic purposes.
