Question

Can you help me please ​

Answer 1

`\approx 14.7 \: {yd}^(2)`

Explanation:

Area of unshaded sector

`= ((360 - 167 )\degree)/(360 \degree) * \pi {r}^(2) \\ \\ 17.8= (197\degree)/(360 \degree) * \pi{r}^(2) \\ \\ \pi{r}^(2) = (17.8 * 360)/(197) \\ \\ \pi{r}^(2) = (6408)/(197) \\ \\ \pi{r}^(2) = 32.5279188 \\ \implies \\Area\: of \: circle= 32.5279188\: yd^2 \\\\ Area \: of \: shaded \: sector \\ \\ = 32.5279188 - 17.8 \\ \\ = 14.7279188 \\ \\ \approx 14.7 \: {yd}^(2)`
