As coal deposits are depleted, it becomes necessary to strip-mine larger areas for each ton of coal. The figure below shows the numb of acres of land per million tons of coal that will be defaced during strip-mining as a function of the number of million tons removed, starting from the present day. acres defaçed per million tons 3 2 million tons of coal extracted (measured from present – day) 1 0.2 1 2 3 4 (a) Estimate the total number of acres defaced in extracting the next 4 million tons of coal (measured from the present day). Draw four rectangles under the curve, and compute their area. Round your estimate to one decimal place.
