Answer:

9.2 cm

Here,

The length of an arc of a sector with theta nag radius'r' is:


(theta)/(360) 2\pi \: r

CD=?

Radius=7.9 cm

theta=66.4

Length of CD


(66.4)/(360) * 2 * \pi * 7.9 \\ = (66.4)/(360) * 2 * 3.14 * 7.9 \\ = 9.1506 \\ = 9.2 \: cm

Hope this helps...

Good luck on your assignment..
