As coal deposits are depleted, it becomes necessary to strip-mine larger areas for each ton of coal. The figure below shows the numbe 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 defaced per million tons 4. 3. million tons of coal extracted (measured from present day) 5. 1 0.4 3 4 Part 1 (a) Estimate the total number of acres defaced in extracting the next 4 million tons of coal (measured from the present day). If four rectangles are drawn under the curve, compute their area. Round vOur estimat to one decimal place
