Haleakala is the volcano that makes up most of the island of Maui. In addition to being broad, it is also tall. If its base on the ocean floor is 19,680 feet below sea level, and its top is 10,023 feet above sea level, how tall is Haleakala from base to top, in feet? Sea level is rising around Maui at a rate of 0.08 inches/year. Assuming this rate does not change, how long will it take for Maui to sink completely beneath the ocean? Reminder: there are 12 inches in one foot. 4 pts
