6. Vocabulary
A sphere is the set of points in three dimensions that are a fixed distance from a given point, the center. A plane that intersects a sphere through its center divides the two halves or hemispheres. The edge of a hemisphere is a great circle.

7. Formula
Sphere r = radius
Hemisphere r = radius

8. Example 1
