Surface Area and Volume of a Sphere

A sphere is the set of all points in space equidistance from a given piont called the center.



Examples:

1) Find the Surface area of a Sphere whose radius equals 4. Leave your answer in terms of Pi.
         SA= 4 pi 4 squ.
         SA= 16 squ pi
         SA= 256 Pi

2) Fine the Volume of a Sphere whose radius equals 4. Leave your answer in terms of Pi.
         V= 4/3 pi 4 cubed
         V= 5.3 pi cubed
         V= 149.8 Pi

Your Turn:
Round all answers to the nearent tenth and leave answers in terms of pi.

1) Find the Surface Area and Volume of a sphere whose radius equals 11.

2) Find the radius of a sphere whose surface area equals 125.

3) Find the volume of a sphere whos surface area equals 300.
