C Correct answer
Explanation

Area of square = 196, so side = 14 cm. The largest semicircle inside a square side has a diameter equal to the side length (14 cm). Thus, the radius is 14/2 = 7 cm.

AI explanation

Taking the square root of the given area of 196 cm2 gives a side length of 14 cm for the square. The diameter of the largest semicircle that fits completely inside the square on one side equals the side length of the square. The radius is half of this diameter, which is 7 cm.
