No, it is not.
cone
The cone has one. Neither the cylinder nor the sphere has any.
Cone: 1/3 ( pi r squared h). sphere: 4/3 pi r cubed
A cone has a base that is a circle. The radius of that circle is its radius.
A sphere sliced by a plane; or a cone.
No, it is not.
cone
A sphere to a cone is the same as a circle is to a triangle but they are both 3 dimensional.
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.
Cicrcle
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
maybe
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.
