A sphere is the set of all points in space that are a fixed distance from a given point called the center of a sphere.

A radius of a sphere connects the center of the sphere to any point on the sphere. A hemisphere is half of a sphere. 

A great circle divides a sphere into two hemispheres

The height of the hemisphere is equal to the radius.

A diameter of a sphere is a segment passing through the center of the sphere with endpoints on the sphere. The circumference of a sphere is the circumference of a great circle.
