Answer:

4618.1 ft³

Explanation:

Volume of the cone:

$V_(cone) = \frac13 \pi r^2 h$

$V_(cone) = \frac13 \cdot \pi \cdot 49 \cdot 12 = 196\pi$

Volume of the cilinder:

$V_(cilinder) = \pi r^2 h$

$V_(cilinder) = \pi \cdot 49 \cdot 22 = 1078\pi$

Total volume is 2*Vcone + Vcilinder = 1470π ≈ 4618.1 ft³
