Best ResponseYou've already chosen the best response.0I can see how to do it tediously you know all three sides of a triangle formed by connecting the centers. use heron's formula to find the area of the triangle. you can find all three angles (use Law of cosines and Law of sines) once you know the angles, you can find the area of each sector the area you want is area of triangle  sum of sectors
