Find the meaure of the central angle the sector area is 169.56 and the radius is 9
BaLLatris [955]
Since the area of a circle is πr^{2}, and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so: c = 360(.6663) ≈ 240°

240 degrees
