__Objectives:__
Define and use the formula to define the surface area of a sphere Define and use the formula for the volume of a sphere

__Definitions:__
Sphere:The set of point that are contained in a circle that equal each other Annulus: This is the center or region between two circles in one plane

=Surface Area and Volume...=

The equation for suface area of a sphere is: S=4(pi)r² with R=the radius You were given this Sphere: Sense we are given the radius you may just fill in the equation: S=4(pi)20² plug it in........ S=5026.54units² = = =//Now for the volume...//=

The equation for the volume of sphere is V=4/3(pi)r³ if we were gived this sphere: we would slso just have to fill in the equation V=4/3(pi)r³ V=4/3(pi)55.23³ plug it in... V=705689.63units³ Want to know more?
