Thread: area of enclosed by lines.

Three circles with centers A, B and C are externally tangent to each other as shown in the figure. Lines EG and DG are tangent to circle C at points F and D and intersect at point G. If each circle has a diameter of 6 inches, find the lenght of DG and the area enclosed by lines FG and GD and arc FD.
