The volume of a cone uses the following formula:

V =  \pi r^{2} \frac{h}{3}

Our diameter is 20 feet, so divide this by 2 to find the radius:

20 \div 2 = 10

We now have all of our values need to fill in the formula. Plug in these values:

\pi = 3.14, r = 10, h = 17

3.14 * 10^{2} *  \frac{17}{3}

3.14 * 100 * 5.67

314 * 5.67 = 1780.38

The volume of the cone is 1780 cubic feet.

See the attached graphic to see this solved for "r".
You should be very careful about stating the units for each of those variables.
time in seconds
radius in meters
mass in kilograms
G = 6.674 x 10^-11 m^3 / (kilograms * seconds²)
