Answer:

12.56 square cm

Step-by-step explanation:

[tex] Central \:angle \:(\theta) = 40°\\

Radius \: (r) = 6 cm[/tex]

Let A be the area of the sector of circle.

[tex] \therefore \: A = \frac{\theta }{360 \degree} \times \pi {r}^{2} \\ \\= \frac{ 40 \degree}{360 \degree} \times 3.14\times {6}^{2} \\ \\ = \frac{ 1}{9} \times 3.14 \times 36 \\ \\ = 3.14 \times 4 \\ \\ = 12.56 \: {cm}^{2} [/tex]
