hey mate!!
area of sector= theta/369×pier^2
area of sector=120/360×22/7×21×21
area of sector=22×21
area of sector=462cm^2
hope it helped!!

area of sector= theta/360 × πr^2
thus, 120/360 × 22/7 × 21× 21
thus, 1/3 × 22 × 3 × 21
thus, 22 × 21
thus, 462 cm^2
thus the area of the sector is 462 sq.cm
hope this helps you
if yes then plz mark this as brainliest...........
