The figure, not drawn to scale, consists of 1 Square C and 1 Circle D whose areas are in the ratio of 4 : 1. Given that
18 of Square C is shaded, what fraction of Circle D is shaded?

Area of Square C is the repeated identity.
Shaded area of Square C is the same as the shaded area of Circle D.
LCM of 4 and 8 = 8
