C) 12 square cm
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. In this case, the diameter is 6 cm, so the radius is half of that, which is 3 cm.
Plugging this value into the formula, we get:
A = π(3)^2
A = 9π
A ≈ 28.27 cm^2
Therefore, the area of the circular region is approximately 28.27 square cm.
