One quality that separates you from all dads is that you consider no project too large as long as it is for your kids. Your youngest has come to you and asked how much rope will wrap around the Earth. Not content to simply answer the question, and being a right and proper geekdad, you endeavor to tie an actual rope around the Earth’s equator. You head to your local building supply superstores (three of them actually) and clear them out of rope. As you’re setting up for your project, your neighbor, being the boring and negative type, challenges you to wrap the rope around the Earth’s equator elevated from the ground by one yard at all points along the rope.

How much rope will you need? (Assume the Earth is perfectly spherical.)
