So here is the problem. My dad designed this umbrella that is to be wrapped with rope. The rope is 1 inch thick, and the umbrella is made of poles that arch away from a center beam extending upward from the ground. My question is how many linear feet of rope would I need if I were to wrap the poles, under and over, starting from the leftmost (or rightmost) pole and working towards the center.

The red arrows are the rope, and 1 foot is to be left at the end after wrapping the rest of the umbrella. I only included arrows on two of the drawings. How would you go about solving this? Let me know if you need any more information. Thanks!!
