#### Answer

$V = 128\pi \approx 402 \text{ cubic yards}$

#### Work Step by Step

RECALL: The volume $V$ of a cylinder is given by the formula $V=\pi{r^2h}$ where r = radius and h = height. The given cylinder has: r = 4 yards h = 8 yards Use the formula above to obtain: $V= \pi(4^2)(8) \\V= \pi(16)(8) \\V = \pi(128) \\V = 128\pi \\V \approx 402 \text{ cubic yards}$
