One face of a washer has an area of 351.9 cm?. The inner radius is 8 cm less than the outer radius. What are the radii? Determine the system of equations for this situation. Let x represent the inner radius of the washer, y represent the outer radius of washer, A represent the area of the washer, and d represent the difference in the radii of the washer. O A. A=1(y² - x²) d=y? -x? OC. A=x(y +x2) O B. A=1(y +x?) d=y-x OD. A=1(y -x) d=y? -x? d=y-x The inner radius is cm and the outer radius is cm. (Round to the nearest whole number as needed.)
