Arc length (s) = radius (r) x θ (in radians)
First, convert 66° into radians using the proportion π = 180°
[tex] \frac{ \pi}{180} = \frac{x}{66} [/tex]
[tex] \frac{66 \pi }{180} = x[/tex]
[tex] \frac{11 \pi }{30} = x[/tex]
s = r θ
= 17 ([tex] \frac{11 \pi }{30}[/tex])
= [tex] \frac{187 \pi }{30} [/tex]
Answer: [tex] \frac{187 \pi }{30} [/tex] ≈ 19.6 cm
