Answer:

141.3 square cm

Step-by-step explanation:

[tex]Area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{200 \degree}{360 \degree} \times 3.14 \times {9}^{2} \\ \\ = \frac{5}{9} \times 3.14 \times 81 \\ \\ = 5 \times 3.14 \times 9 \\ \\ = 15.70\times 9 \\ \\ = 141.3 \\ \\Area \: of \: sector = 141.3 \: {cm}^{2} [/tex]
