A cloud’s temperature The temperature T within a cloud at height h (in feet) above the cloud base can be approximated using the equation ,where B is the temperature of the cloud at its base. Determine the temperature at 10,000 feet in a cloud with a base temperature of 55°F and a base height of 4000 feet. Note: For an interesting application involving the three preceding exercises, see Exercise in the Discussion Exercises at the end of the chapter.

Earth’s surface area Water covers 70.8%, or about 361 × 106 km2, of Earth’s surface. Approximate the total surface area of Earth
