Since the diameter is , the radius is . So
Start with the volume of a cylinder formula.
Plug in and .
Replace with (note: Use more digits of to get better accuracy).
Square to get .
Multiply , and to get (this value is approximate).
So the volume is approximately 461.58 cubic inches.
So the pipe can hold approximately 461.58 cubic inches of water.
