Answer :

Explanation

Volume 2916 cubit feet

Landing pad square 54 feet each side

Part A

[tex]\begin{gathered} V=54*54*h \\ 2916=54*54*h \\ h=\frac{2916}{54*54} \\ h=1\text{ feet } \end{gathered}[/tex]

Part B

[tex]\begin{gathered} V=\pi r^2h \\ r=\sqrt{\frac{V}{\pi h}} \\ r=\sqrt{\frac{2916}{3.14*1}} \\ r=30.47\text{ feet} \end{gathered}[/tex]

The diameter would be 60.94 feet
