Answer:
107.39 units
Step-by-step explanation:
CD = 18 units (CD is the diameter of the circle)
r = 18/2 = 9 units
[tex]l(\widehat{ED}) = \frac{ m\angle DAE }{360 \degree} \times 2\pi \: r \\ \\ = \frac{76 \degree}{360 \degree} \times 2 \times 3.14 \times {(9)}^{2} \\ \\ = \frac{38,659.68}{360} \\ \\ = 107.388 \\ \\ \approx \: 107.39 \: units[/tex]
