A Correct answer
Explanation

For a circle of radius r, circumference = 2πr and area = πr². When r = 6 cm, circumference = 12π and area = 36π. The ratio 12π:36π simplifies to 1:3 by dividing both terms by 12π. Option B (2:3) is incorrect because it doesn't account for the π in both terms cancelling out.
