21/05/2016 If we know the height and diameter of the cylinder, we can calculate the helical length. If you were to take the cylinder and roll it out, the helical length would form the hypotenuse of a triangle made by the height of the cylinder, and it’s circumference. So, in this example, if the Height of the cylinder = 10 feet (120 inches), and the Diameter = 5 feet (60 inches), then the Circumference ...
