Answer:
15 cm
Step-by-step explanation:
The central angle for this problem is:
[tex]\frac{7 \pi}{10}rad \approx 2.2 rad[/tex]
To solve this problem, we have to use an expression that relates, central angle, arc length and radius, which is:
[tex]s=\theta r[/tex]
So, we isolate the radius and solve:
[tex]r=\frac{s}{\theta}=\frac{33cm}{2.2rad}=15cm[/tex]
Therefore, the right answer is the second option.
