what is the area of a circular region whose diameter is 6 centimeters?
6pi cm
9pi cm
12pi square cm
9pi square cm
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is 6 cm, the radius is half of that, which is 3 cm.
Plugging in the radius into the formula:
A = π(3)^2
A = π(9)
A = 9π square cm
Therefore, the area of the circular region is 9π square cm.
