Extra Credit: An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume), and apply a formula to convert a body fat percentage. Formula: BF = (4.57/p - 4.142)x100 (where BF = body fat and p = density in g/cm³. A man weighs 260 pounds. His total body volume is measured by a cylinder with a height of 180 cm and a radius of 14 cm. Find his body fat percentage, based upon the given formula (to the nearest percent).
