Answer:

7.722 cm^2

Explanation:

To find the area of the shaded area, you need to subtract the area of the circle from the area of the square. The area of the square is easy: just the square of the side length. In this case, the area is 6^2=36 square centimeters. The area of the circle is:


\pi r^2 = \pi (3)^2 = 9\pi \approx 28.278

Thus, the area of the shaded region is 36-28.278 = 7.722 square centimeters.
