Find the area of the shaded region in the figure. Use the key for What is the diameter of the outer circle? D= 5 in. What is the diameter of the inner circle? d = 3.5 in. (Type an integer or a decimal.) w, use the formula A=(D² - d²) to find the area of the shaded region. A = = x (0²-0²) = = [(5 in.)² – (3.5 in.)²] Substitute 5 in. for D and 3.5 in. for d. Simplify. (Simplify your answer. Round to the nearest tenth as needed.) C
