V=%284%2F3%29pi%2Ar%5E3 Start with the volume of a sphere formula.


V=%284%2F3%29pi%2A%283%29%5E3 Plug in r=3.


V=%284%2F3%29%283.14%29%2A%283%29%5E3 Replace pi with 3.14 (note: Use more digits of pi to get better accuracy).


V=%284%2F3%29%283.14%29%2A%2827%29 Cube 3 to get 27.


V=%284%2F3%29%2884.78%29 Multiply 3.14 and 27 to get 84.78


V=113.04 Multiply 4%2F3 and 84.78 to get 113.04


So the volume is approximately 113.04 cubic inches.
