The Solution:

Given that the volume of the cylindrical tank is:


\begin{gathered} V=\pi*\text{ square of radius}*\text{ length of the tank} \\ V=\pi r^2h \end{gathered}

In this case,


\begin{gathered} \text{ V=volume of the tank=?} \\ r=\text{ radius=12 ft} \\ h=\text{ length of the tank=20 ft} \end{gathered}

Substituting these values in the above formula, we get


V=20*12^2*\pi=9047.787\approx9047.8\text{ cubic feet}

Therefore, the correct answer is approximately 9047.8 cubic feet.
