A circle with radius 3: area = pi r^2. Approximate value using pi = 3.14.

Explanation:
Area of a circle is π times the radius squared. With a radius of 3, r^2 is 9. Using π ≈ 3.14, multiply 3.14 by 9 to get 28.26. So the approximate area is 28.26 square units. The other numbers come from using a different radius or a different π value, but with r = 3 and π ≈ 3.14, 28.26 is the correct result.
