A Correct answer
Explanation

Perimeter (circumference) = 2 * pi * r = 2 * (22/7) * 14 = 2 * 22 * 2 = 88 cm.

AI explanation

The perimeter of a circle is its circumference, which is calculated using the formula C = 2 * pi * r. Substituting the radius of 14 cm gives C = 2 * (22/7) * 14 = 88 cm. The perimeter is 88 cm.
