Step-by-step explanation:
Area of sector of circle=(angle/360)*π*r*r
=(120/360)*3.14*12*12
=150.72 sq cm
Area of the triangle made by the two radii and one chord subtended by the angle 120°
=1/2*12√3*6
=1/2*12*1.73*6
=62.28
Area of segment of circle=Area of sector - Area of the triangle
=150.72-62.28
=88.44 sq cm
Hopefully I think this will help you!
If you didn't understand the answer, please comment me I will try to explain it better with the help of diagram.
