The volume of a cone is three hundred cubic kilometers. If the radius of the base is 9 kilometers, what is the height of the cone? Use three point one four for pi. Show your work and round to the nearest tenth.

V = 3.14r^2h /3 =
3.14*9^2*h / 3 = 300 km^3
Multiply both sides by 3,solve for L
3.14**81*L = 900
L = 900 / (3.14*81) = 3.5 km^3
