28.50x + 110.99(14-x)=811.45
distribute
28.50 x + 1553.86-110.99x =811.45
combine like terms
-82.49x+1553.86=811.45
subtract 1553.86 from each side
-82.49x =-742.41
divide by -82.49
x=9

Answer:
60
m³
Step-by-step explanation:
Use the cone volume formula, V = r²
If the diameter is 12 m, the radius will be 6 m.
Plug in the height and radius into the formula, and solve:
V = r²
V = (6²)
V = (36)
V = 60
So, the volume of the cone is 60 m³
