A machining company manufactures washers. The dimensions of the washer are shown in the figure, and the inner and outer radii can be +/-2% of the indicated values. This range of acceptable values is called the tolerance. A) Write compound inequalities for the acceptable dimensions for the inner radius r and outer radius R. B) Write an eqaution for the area of the face of the washer in terms of r, R, and pi. C) Write a compound inequality for the area, to the nearest tenth of a square centimeter, of the face of the washer. (hint:Find the smallest possible area and the largest are and the largest possible area.) PS: I really only need help on b and c. Please help
