Find the area of the segment AOB of angle 120°and radius 18 cm. |
|
Answer» Step-by-step explanation: Given: Radius(r)=18cm and angle=120 Therefore, 120/360*22/7*(21)^2 =1/3*22/7*21*21 =22*21 =462cm^2 Finding AREA of AOB =1/2*b*H angle OMB=angle OMA = 90 DEGREE. therefore OA=OB OM=OM Therefore OMA = OMB =angle AOM=angle BOM
