The formula for the volume of a cylinder is
[tex]V=\pi \times {r}^{2} \times h[/tex]
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.
[tex]V = \pi \times {3}^{2} \times 8 \\ V = \pi \times 9 \times 8 \\ V = \pi \times 72 \\ V = 3.14 \times 72 \\ V = 226.0800000000003[/tex]
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,
[tex]226.0800000000003 \times 3 \\ = 678.2400000000017 [/tex]
