| The area of a circle is calculated using the formula pi * r^2

The larger circle of the ball is the section passing through the center of the ball, which means that its radius coincides with the radius of the ball.

By the condition of the problem, pi * r^2 = 5.

The surface area of the ball is calculated by the formula:

4pi * r^2 = 4 * 5 = 20

Answer: 20
