Circle c is shown. line segments a c and b c are radii. a line is drawn from point d on line a c to point e on line c b to form a line segment with length 5. the area above the line with length 5 is shaded. the length of d c is 3. point f is on the outside of the shaded area. the radius of circle c is 6 units and the measure of central angle acb is startfraction pi over 2 endfraction radians.
