The formula for the volume of a cone is $V=\frac{r^2\pi h}{3}$ where $r=$radius and $h$=height. The diameter is 3.1 feet, which means that the radius is 1.55 feet. So after substituting 11 for $h$ and 1.55 for $r$ into the volume equation, we have that the volume of the cone is approximately 27.67 $ft^3$.
