The figure, not drawn to scale, consists of 1 Square D and 1 Circle E whose areas are in the ratio of 3 : 1. Given that
29 of Square D is shaded, what fraction of Circle E is shaded?

Area of Square D is the repeated identity.
Shaded area of Square D is the same as the shaded area of Circle E.
LCM of 3 and 9 = 9
