Question

Part DSuppose the cylindrical water tank has a radius of 12 feet.

Answer 1

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.
