Answers 82. Trenton, New Jersey (40.2°N, 74.8°W), is located north of the equator, and Ayacucho, Peru (13.2°S, 74.2°W), is located south of the equator. The longitudes are nearly the same indicating that the cities are roughly due north-south of each other. Use the difference in latitude to approximate the distance between the cities. 83. A pulley is 16 cm in diameter. a. Find the distance the load will rise if the pulley is rotated 1350°. Find the exact distance in terms of n and then round to the nearest centimeter. b. Through how many degrees should the pulley rotate to lift the load 100 cm? Round to the nearest degree. Load Answers 84. A pulley is 1.2 ft. in diameter. a. Find the distance the load will rise if the pulley is rotated 630°. Find the exact distance in terms of a and then round to the nearest tenth of a foot. b. Through how many degrees should the pulley rotate to lift the load 24 ft? Round to the nearest degree.
