Answer:
The volume of a cone can be calculated using the formula 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 cone, we need to divide the diameter by 2:
r = 3.6 feet / 2 = 1.8 feet
Now we can plug in the values we have into the formula and simplify:
V = (1/3)π(1.8 feet)^2(2.6 feet)
V ≈ 10.91 cubic feet
Therefore, the volume of the cone is approximately 10.91 cubic feet.
