The circular pool has a diameter of 25 feet. What is its approximate area in square feet?

Explanation:
Area of a circle is π times the radius squared. The diameter is 25 ft, so the radius is 12.5 ft. Then the area is π × (12.5)^2 = π × 156.25 ≈ 3.1416 × 156.25 ≈ 490.9 square feet. Since the question asks for an approximate area, about 490 square feet is the best fit. The other options are farther from 490 (for example, 500 is a bit high, 450 a bit low, 520 much higher), so 490 is the closest approximation.
