To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, so the radius is 3 inches. Plugging this into the formula, we get A = π(3)^2 = 9π square inches. Since π is approximately 3.14, the area is approximately 28.26 square inches.
