The average raindrop has a diameter of 2.55mm. Columbus, OH has an average rainfall of 38.52 inches per year. You know how to find the volume of a sphere and diameter and volume= L*W*H and that 1 meter = 39.37 in. Leap year = 366 days/year. How many rain drops fall on a square meter in Columbus, OH per day in a leap year?
