Answer:
[tex]V=3141.59\ \text{feet}^3[/tex]
Step-by-step explanation:
Given that,
The height of the pile, h = 25 feet
The radius of the pile, [tex]r=1.2\times 10^2\ ft[/tex]
We need to find the volume of the pile of cone. The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{1}{3}\pi \times (1.2\times 10^2)\times 25\\\\V=3141.59\ \text{feet}^3[/tex]
So, the required volume of the pile is [tex]3141.59\ \text{feet}^3[/tex].
