Part A A rope is wrapped around a wheel with radius 2 feet. If the radius of the wheel is increased by 1 foot to a radius of 3 feet, by how much must the rope be lengthened to fit around the wheel? Part B Consider a rope wrapped around the Earth's equator. The radius of the Earth is about 4000 miles. That is 21,120,000 feet. Suppose now that the rope is to be suspended exactly 1 foot above the equator, By how much must the rope be lengthened to accomplish this?
