Let us find the surface area of the ball using the formula and approximately taking the value of the constant Pi rounded to hundredths.

S = 4πr ^ 2, where r = 8 cm is the radius of the ball and π ≈ 3.14.

S = 4 * 3.14 * 8 ^ 2 = 4 * 64 * 3.14 = 803.84 cm2.

Answer: the surface area of the ball is S = 803.84 cm2.
