The area of a circle with a diameter of 72 feet is approximately which value?

Explanation:
Start with the circle area formula. The diameter is 72 ft, so the radius is 72/2 = 36 ft. The area is A = πr^2 = π(36)^2 = 1296π ≈ 1296 × 3.1416 ≈ 4071.5 square feet. The value closest to this among the given options is 4071 sq ft, so that is the best approximate answer.
