Answer:
Area of Sector = 226.08
Step-by-step explanation:
What is the area of segment in a circle of radius 12 cm and its sector angle is 120°
Area of Circle = πr²
where r = radius
Area of Sector = (sector angle/360) (area of circle)
=> Area of Sector = (120/360) * πr²
r = 12 cm
=> Area of Sector = (1/2)π12²
=> Area of Sector = 72 π
=> Area of Sector = 226.08 (using π = 3.14)
