Answer:

15 cm

Explanation:

The central angle for this problem is:


(7 \pi)/(10)rad \approx 2.2 rad

To solve this problem, we have to use an expression that relates, central angle, arc length and radius, which is:


s=\theta r

So, we isolate the radius and solve:


r=(s)/(\theta)=(33cm)/(2.2rad)=15cm

Therefore, the right answer is the second option.
