The formula for the volume of a cylinder is


V=\pi * {r}^(2) * h

Where:

V is volume

r is radius of the circle of the cylinder

h is the height of the cylinder, technically the length in this problem

All you have to do is plug in the values for each.


V = \pi * {3}^(2) * 8 \\ V = \pi * 9 * 8 \\ V = \pi * 72 \\ V = 3.14 * 72 \\ V = 226.0800000000003

Because the instructions state not to round your answer...

Final answer is 226.0800000000003

cubic inches.

UNLESS! The question is asking for the entire length of the cylinder, which shows three equal parts.

If so,


226.0800000000003 * 3 \\ = 678.2400000000017
