Heya !!!
This is your answer.
Given ---》》》》
Radius = 7 cm.
theta = 120 deg.
Area of sector = theta/360 × pi × r^2.
= 120/360 × 22/7 × 7 × 7.
= 1/3 × 22 × 7
= 154/3 cm^2.
= 51.33 cm^2.
Hence the area is 154/3 or 51.33 cm^2.
Hope it helpz

radius= 7 centimetre
angle= 120 degree
area of sector= theta/360*pi r²
= 120/ 360*22/7*7*7
= ⅓*22*7 = 154/3cm²
angle= 120 degree
area of sector= theta/360*pi r²
= 120/ 360*22/7*7*7
= ⅓*22*7 = 154/3cm²
