The volume of the pile is 5670.6 ft³
Explanations:The volume of a cone is given by the formula:
[tex]V\text{ = }\frac{\pi r^2h}{3}[/tex]The base diameter of the cone, d = 38 feet
The radius, r = d/2
r = 38/2
r = 19 feet
The height of cone, h = 15 feet
Substituting the values of r and h into the formula for the volume of a cone:
[tex]\begin{gathered} V\text{ = }\frac{\pi\times19^2\times15}{3} \\ V\text{ = }\pi\times19^2\times5 \\ V\text{ = }3.142\text{ }\times361\times5 \\ V=5670.6ft^3 \end{gathered}[/tex]The volume of the pile is 5670.6 ft³
