Help please rn help

Answer 1

Area of the large semicircle

`= \pi{r}^(2) / 2`

`= (22)/(7) * 12 {}^(2) * (1)/(2)`

`= (11)/(7) *12 * 12`

`= (11)/(7) * 144`

`= 226.28`

Area of the small semicircle

`= \pi {r}^(2) / 2`

`= (22)/(7) * 6 {}^(2) * (1)/(2)`

`= (11)/(7) * 6 * 6`

`= (11)/(7) * 36`

`= 56.57`

Area of the figure

`= 226.28 - 56.57`

`= 169.71 {cm}^(2)`
