<span>The formula for calculating the cone volume is: 
</span>V =  \frac{  \pi *r^2* h}{3}
<span>
Data:
h (height) = 12 in
r (radius) = 9 in
Use: </span>\pi \approx 3.14

Solving:
V = \frac{ \pi *r^2* h}{3}
V = \frac{ 3.14 *9^2* 12}{3}
V = \frac{ 3.14 *81* 12}{3}
V = \frac{3,052.08}{3}
V = 1,017.36 \to \boxed{\boxed{V = 1,017.4\:in^3}}\end{array}}\qquad\quad\checkmark
