Find the area of the shaded region formed by chord AB. If you need to round, round to the nearest tenth of a square centimeter.
+36916 Calculate the entire area of the circle pi r^2 = 64 pi
the upper R quadrant is 1/4 of this = 16 pi
now subtract the area of the triangle 1/2 b h = 1/2 8*8 = 32
chord area = 16 pi - 32 = ......... cm^2
