Area of a circle with radius 5, using pi ≈ 3.14, is approximately 78.5. Which option matches closest?

Explanation:
Area of a circle is π times the radius squared. With a radius of 5, r^2 is 25. Using π ≈ 3.14, 25 × 3.14 equals 78.5. That makes the option showing 78.5 the exact result under this approximation, so it’s the closest match. The other numbers are just rounded versions and don’t match the precise calculation.
