Solve the Problem $\mathrm{V}$ 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 $\mathrm{V}$ of the tank can be computed using the formula $\mathrm{V}=\frac{4}{3} \pi\left(\frac{\mathrm{x}}{2}\right) ^{3}+\pi y\left(\frac{\mathrm{x}}{2}\right) ^{2}$ . If $\mathrm{x}=$ $3.4 \mathrm{ft}$ and $\mathrm{y}=5.8 \mathrm{ft}$ , calculate the volume of the tank. Use the approximation $\pi \approx 3.14$ .

A) $73 \mathrm{ft}^{3}$
B) $135 \mathrm{ft}^{3}$
C) $30 \mathrm{ft}^{3}$
D) $37 \mathrm{ft}^{3}$
