The volume of a cone is $\frac13 \pi\; r^2 h$ where $r$ is the radius, $h$ is the height, and $\pi$ is approximately 3. 1416. This will give you an answer of $V$ cubic feet. To determine the volume in cubic yards use Goggle. Once you know the value of V type into the Goggle search window V cubic feet in cubic yards. Penny
