App4. Measurement The radius of the earth is approximately 6,400 km (roughly 4,000 miles). Suppose a cable was laid all the way around the equator on the surface of the earth.
(a) How much longer would the cable have to be if it was to be raised 1 meter above the surface all the way around the earth?
(b) Repeat part (a) for a cable around Jupiter, whose approximate radius is 71,400 km (roughly 44,400 miles).
