5. Sphere
The set of all points in space equidistant from a given point (the center)

7. Great Circle
The largest cross section of a sphere; shares the same radius and center as the sphere Ex: The Earth’s equator

8. Ex 1: Given the diameter or radius, find the SA and V of each sphere
a. r= b. d=12

9. Ex 2: Given the circumference of the great circle of the sphere, find the radius and Surface Area
a. C=36pi b. C=52pi

10. Ex 3: Given the surface area of the sphere, find the Volume:
a. SA = 845 in sq. B. SA=144pi m sq

11. Ex 4: Given the volume of the sphere, find the surface area
a. V=288pi ft cubed b cm cubed
