Question

What is the area of segment in a circle of radius 12 cm and its sector angle is 120°?
d) 79.82
c) 78.82
a) 76.82
b) 77.82​

Answer 1

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)
