Each revolution is the circumference of the windlass drum. We know the diameter is .8 meter. Let n be the number of revolutions and note that circumference of a circle is pi * D, then we can write the following formula,
length of rope = n * pi * D where * means multiply, then
length of rope = 16 * pi * .8 = 40.21 meters
