Surface+Area+and+volume+of+spheres.

Objectives** -Define and use the fourmula for the surface area of a sphere. -Define and use the formula for the volume of a sphere.
 * __Sphere Volume and Surface Area Theorem__
 * Surface Area of Spheres SA= 4¶ r²

Volume Formula: //V = (4/3)//¶//r³// SPHERE= The set of all points in space that are the same distance from a given point known as the center of the sphere.**
