A car starts from a point at 2:00 pm. and travels north at 40 mph. Another car starts from the same point at 3:00 pm. and travels west at 50 mph. After the second car has traveled 1 h, at what rate is the distance between the two cars changing? A spherical ball is measured to have a radius of 6 cm with a possible measurement error of :0.1rm cm. Use the differentials to estimate the percentage error in computing the volume of the ball.
