A circular area with a radius of 10 feet has an area of approximately how many square feet?

Explanation:
The key idea is using the circle area formula A = π r^2. With a radius of 10 feet, you square the radius to get 100, then multiply by π. Using π ≈ 3.14 gives 100 × 3.14 ≈ 314 square feet. So the area is about 314 square feet. The other numbers don’t fit because they would require a different radius or a less precise value for π.
