**Steve**, Monday, December 31, 2012 at 11:52pmthe circle centers form an equilateral triangle with side 10.

area of triangle is thus √3/4 10^2 = 25√3

each side of the triangle subtends an angle of π/3, and the segment formed has area 1/2 *25*(π/3-√3/2) = 25/12 (2π-3√3).

Subtract the area of the 3 segments from the triangle, leaving

25√3 - 25/4 (2π-3√3) =~ 36.5

you can massage that if you want.
