I have to calculate the area of the sector created by ADB.
http://curriculum.kcdistancelearning.com/courses/GEOMxHSWA10/b/assessments/CCirclesExam/Geometry_7_Exam_102q3.gif
I know the area of the circle, which is 254.34, do I need that to solve this? If so, how do I do that?

360  Angle ACB (Which is 180 + 20) = 160 So for 360 degrees, area is 254.34 for 160 degrees in the same circle, area is..? Set up a proportion, then solve it :)
