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

Area of Square S is the repeated identity.
Shaded area of Square S is the same as the shaded area of Circle T.
LCM of 3 and 13 = 39
Fraction of Circle T that is shaded
