A Correct answer
Explanation

Area of a circle = pi * r^2. Using pi = 22/7 and r = 7, Area = (22/7) * 7 * 7 = 22 * 7 = 154.

AI explanation

The formula for the area of a circle is pi multiplied by the square of the radius. Substituting the radius of 7 cm gives (22/7) * 7 * 7. This simplifies to 22 * 7, resulting in 154 sq. cm. The result is 154.
