B Correct answer
Explanation

Area of square = 196, so side = 14. Diameter of circle = 14, so radius = 7. Circumference = 2 * pi * r = 2 * (22/7) * 7 = 44 cm.

AI explanation

Taking the square root of the square's area gives a side length of 14 cm, which equals the diameter of the circle. The circumference formula is pi times diameter, so we multiply 22 over 7 by 14 to get 44 cm. The correct answer is 44 cm.
