Solve the Problem $V$ Of the Tank Can Be Computed Using the Formula

Multiple Choice

Solve the problem.
-Liquid propane fuel is frequently stored in tanks that are shaped like the one shown in the figure below. The volume $V$ of the tank can be computed using the formula $V=\frac{4}{3} \pi\left(\frac{x}{2}\right) ^{3}+\pi y\left(\frac{x}{2}\right) ^{2}$ . If $x=$ $2.7 \mathrm{ft}$ and $\mathrm{y}=5.8 \mathrm{ft}$ , calculate the volume of the tank. Use the approximation $\pi \approx 3.14$ .

A) $21 \mathrm{ft}^{3}$
B) $74 \mathrm{ft}^{3}$
C) $43 \mathrm{ft}^{3}$
D) $16 \mathrm{ft}^{3}$
