The diameter of a soccer ball is approximately 0.269 m. The diameter of the moon is 3.476 * 106 m. How many soccer balls does it take to equal the surface area of the moon? Assume that the moon is a sphere with flat terrain. What percentage of Avogadro's number is the calculated number of soccer balls? Take the value of Avogadro's number to be 6.02 x 1023 The number of soccer balls required to equal the surface area of the moon is 1014, and the percentage of the number of soccer balls to Avogadro's number is approximately x 10-86
