The length of the arc intercepted by the angle is [tex]\frac{\pi}{6}[/tex] times the length of the radius
From the question, we are to determine the length of the arc intercepted by the angle
The length of an arc can be calculated by using the formula,
[tex]l =\frac{\theta}{360 ^\circ} \times 2\pi r[/tex]
Where [tex]l[/tex] is the length of the arc
[tex]\theta[/tex] is the central angle
and r is the radius
From the given information,
θ = 30°
∴ [tex]l =\frac{30 ^\circ}{360 ^\circ} \times 2\pi r[/tex]
[tex]l = \frac{1}{12}\times 2 \pi r[/tex]
[tex]l = \frac{2 \pi}{12}\times r[/tex]
[tex]l = \frac{ \pi}{6}\times r[/tex]
Hence, the length of the arc intercepted by the angle is [tex]\frac{\pi}{6}[/tex] times the length of the radius
