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

Area of Square B is the repeated identity.
Shaded area of Square B is the same as the shaded area of Circle C.
LCM of 4 and 13 = 52
