Hey mate ,

Let the bigger semicircle be I

and the smaller semi circle be II

Radius of bigger (r) semi circle = 2 cm

Radius of smaller(r') semi circle = 1 cm

Area Of Semi Circle = Area of Circle / 2

 = \frac{ \: \pi{r}^{2} }{2}

Area of shaded region = Area of bigger semicircle - Area of smaller circle

 =  \frac{\pi {2}^{2} }{2}  -  \frac{\pi {1}^{2} }{2}

 =  \frac{\pi}{2} (4 - 1)

 =  \frac{3\pi}{2}  = answer

 =  \frac{3 \times 3.14}{2}

 = 4.71 {cm}^{2} (approx.)

HOPE YOU FIND IT HELPFUL !
