To find the approximate area of the shaded region, we can use the formula for the area of a circle: A = πr^2, where π is approximately equal to 3.14, and r is the radius. It looks like the radius of the circle is 12 cm, so the formula becomes A = π(12)^2, which is approximately equal to 145.1. So, the approximate area of the shaded region is around 145.1 cm^2.
