B Correct answer
Explanation

Area of a circle = pi * r^2. With r = 4 and pi = 3.14, Area = 3.14 * 16 = 50.24.

AI explanation

To find the area of a circumcircle, the formula A = pi * r^2 is used, where r is the radius of the circle. Substituting the given radius of 4 cm and using 3.14 for pi gives A = 3.14 * 4^2. Solving this results in A = 3.14 * 16 = 50.24 square cm.
