The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
Since the diameter of the circle is 4 ft, the radius is half of the diameter, which is 4/2 = 2 ft.
Plugging in the radius into the formula, we get:
A = π(2)^2
A = π(4)
A = 4π
Therefore, the area of the circle is 4π square feet.
