Could someone help me with this problem? It is supposed to have a figure with it, but all the figure is, is the shape of a ring.
the top side of a circular medallion made of a circular piece of colored glass is surrounded by a metal frame. If the radius of the medallion is r centimeters and the width of the metal frame is s centimeters, then in terms of s and r, what is the area of the metal frame, in square centimeters?
a) pi(r-s)^2
b) pi(r^2-s^2)
c) 2pi(r-s)
d) pi(r)(2r-s)
e) pi(s)(2r-s)
Thanks very much for anyone who has the time for this one. [/img]
