Explanation:
The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.
To find the radius of the base, we can use the formula for the circumference of a circle: C = 2πr.
So, we have:
C = 29.516 feet
2πr = 29.516 feet
r = 29.516 / (2π) feet
r ≈ 4.698 feet
Now we can substitute the values of r and h into the formula for the volume of a cone:
V = (1/3)πr^2h
V = (1/3)π(4.698^2)(7)
V ≈ 216.75 cubic feet
Therefore, the volume of the sculpture is approximately 216.75 cubic feet.
