The volume of a cylinder is represented by:

We know that r is equal to

, and d in this case is 9 in. Therefore, r = 4.5 in.
Then, using 3.14 for

, and 15 in. for height, we can solve for the volume of the cylinder:



By using this equation, we were able to determine that the volume of this cylinder is
.
