The area of a circle with radius 3 cm is approximately what square centimeters? Use pi ≈ 3.14.

Explanation:
Area of a circle is found with A = πr^2. So you square the radius and multiply by π. With radius 3 cm, r^2 = 9. Using π ≈ 3.14, A ≈ 3.14 × 9 = 28.26 square centimeters. That Value matches the given options, since 28.26 cm^2 is the result from the calculation, while the other numbers are looser roundings or farther from 28.26.
