12Y-47: A manufacture makes fishing line rated by how much the fish weighs in increments of 5 pounds starting with 5 pounds. Using the same material, the rating is directly related to the cross sectional area of the line. If the diameters of each line are 2.0mm, 2.8mm, 3.5mm, 3.9mm, and 4.5mm, respectively, what diameter of line would be needed to land a 150 pound blue marlin in inches? Ans: .431
Not sure if I'm doing this completely wrong or messing up while putting into HP.
