To find the volume of the smokestack, you can use the formula for the volume of a cylinder, which is:
Volume = π * radius^2 * height
First, convert the height from feet and inches to just feet:
40 feet 2 inches = 40.167 feet (since 1 inch is equal to 1/12 of a foot)
Now, you can calculate the volume using the given values:
Radius = 9 feet
Height = 40.167 feet
Volume = π * (9 feet)^2 * 40.167 feet
Volume ≈ 10,218.27 cubic feet
So, the volume of the smokestack is approximately 10,218.27 cubic feet.
