The area of the circle can be calculated using the formula A = πr^2 where r is the radius of the circle.
Given that the diameter is 12 feet, the radius would be half of that, so r = 12/2 = 6 feet.
Now, plug in the values into the formula:
A = 3.14 * 6^2
A = 3.14 * 36
A = 113.04
Rounded to the nearest tenth, the area of the circle is 113.0 ft^2.
So the answer is:
113.0 ft^2
