Hanging a Pipe A contractor wants to pick up a 10-ft-diame-ter pipe with a chain of length 40 ft. The chain encircles the pipe and is attached to a hook on a crane. What is the distance between the hook and the pipe to the nearest thousandth of a foot? (This is an actual problem that an engineer was asked to solve on the job.)
