Explanation

To compute for the volume of the cylindrical tank, use the formula:

Volume = Area of a circle x Height of the cylinder

\(=\pi(\text { diameter })^{2} / 4 \times \text { height }=\pi(\text { diameter })^{2}(\text { height }) / 4\)

\(= 3.14{(4.5)^2} \times 18/4 = 3.14 (4.5)(4.5)(4.5)\)

Volume = 286.13 cubic feet
