ANSWER
The volume is 3624.35 ft³
EXPLANATION
The volume of a cone with height h and radius r is:
[tex]V=\frac{1}{3}\pi r^2h[/tex]In this problem h = 19ft and r = d/2 = 27ft/2 = 13.5ft. The volume of this cone is:
[tex]\begin{gathered} V=\frac{1}{3}\cdot3.14\cdot13.5^2\cdot19 \\ V=3624.345ft^3\approx3624.35ft^3 \end{gathered}[/tex]
