What is the area of the secondary clarifier with a diameter of 45 feet?

Explanation:
Circle area is found with A = πr^2. With a diameter of 45 ft, the radius is 22.5 ft, so A = π × (22.5)^2 = π × 506.25 ≈ 1,590 ft^2. The correct choice is the one near 1,590 ft^2. The 1,000 ft^2 option is too small, the 2,000 ft^2 option is too large, and the 1,800 ft^2 option is slightly larger than the calculated value.
