A crop fertilizer machine has fertilized the shaded area of a circular field . If measure of angle BDC = 48 find the area that has been fertilized , to the nearest tenth of a square meter . IMPORTANT Please notice we need to account for the AREA of segment BD which is the unshaded area at the bottom of the circle .
The shaded area is the area of the circle minus the unshaded areas (the area of the sector BAC and the area of segment BD) How can I calculate the measurement of angle BAD?? Please help. Thanks
