ConeConeKerucutKerucut

A three dimensional shape with a circle at its base and a pointed vertex.

A cone has a circular base and a vertex that is not in the same plane as a base.In a right cone, the height meets the base at its center.

The height of a cone is the perpendicular distance between the vertex and the base.The slant height of a cone is the distance between the vertex and a point on the base edge.

Radius – Is a segment that has one endpoint the center & the other endpoint on the sphere.

Diameter – A segment passing through the center with both endpoints on the sphere.

Great Circle – A cross-section of a sphere that also contains the center of the sphere.
