Hi,
Is there a better way to solve this without pluging values?
Thank you for your help!!

The figure shows the top side of a circular medallion made of a circular piece of colored glass surrounded by a metal frame, represented by the shaded region. If the radius of the medallion is r centimeters and the width of the metal frame is centimeters, then in terms of s and r, what is the area of the metal frame, in square centimiteres?
