Difference in areas = (22/7 x 21 x 21 - 120/360* 22/7 x 21 x 21) cm2
= (1 - 1/3)(66x21) xm2
= 66x7x2 cm2
= 924 cm2
= (1 - 1/3)(66x21) xm2
= 66x7x2 cm2
= 924 cm2

Given theta = 120 and radius r = 21cm.
We know that Area of the sector = theta/360 * pir^2
= 120/360 * 22/7 * 21 * 21
= 462 cm^2.
Hope this helps!
