Step-by-step explanation:

Area of sector of a circle = $\frac{\theta}{360} * \pi \: r^{2}$

Here,  

• $\theta$ = 120°

Area of Major Sector = $\frac{120}{360} * (\frac{22}{7} ) \: 3^{2}$

= 66/ 7

Area of Minor Sector =  $\frac{120}{360} * (\frac{22}{7} ) \: 2^{2}$

= 88/ 21

Area of the shaded portion = Area of Major Arc - Area of Minor Arc

= 66/ 7 - 88/ 21

= 110/ 21
