Answer:
To find the volume of a cone with radius 9 feet and height 4 feet, we can use the formula:
V = (1/3) * π * r^2 * h
Plugging in the values:
V = (1/3) * π * (9^2) * 4
Calculating:
V = (1/3) * π * 81 * 4
V ≈ 108.19 cubic feet
Therefore, the volume of the cone is approximately 108.19 cubic feet (rounded to two decimal places)
