Ma Bell want to place a telephone cable around the equator. She adds 50
feet to the length of the cable beyond what is required. This slack in the
cable allows the cable to be strung up above the ground. How high up from
the surface of the earth will the cable stand? You can assume that the
earth is a perfect sphere.

In your mind, run a sanity check on your answer to see if it makes sense.
