Answer
$980\text{ ft}^3$
Work Step by Step
The volume $(V)$ of a cone is given by the formula $V=\frac{1}{3}\pi{r^2}h$ where $r$=radius of the circle and $h$=height of the cone.
The given cone has:
$h=15$ feet
$r=14$ feet
Thus, using the formula above gives:
$V=\frac{1}{3}\pi(14^2)(15)
\\V=980\text{ ft}^3$
