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

Area of Square V is the repeated identity.
Shaded area of Square V is the same as the shaded area of Circle W.
LCM of 4 and 12 = 12
