ANSWER
The length of arc AB is π units.
EXPLANATION
The length of an arc of a circle is calculated using the formula:
[tex]l = \frac{ \theta}{360} \times 2\pi \: r[/tex]
Where [tex] \theta = 30 \degree[/tex]
is the angle of sector and r=6 units is the radius of the circle.
We substitute these values into the formula to find the length of arc AB.
[tex]l = \frac{30}{360} \times 2 \times \pi \: \times 6[/tex]
[tex]l = \pi[/tex]
The length of the arc is π units.
So put 1 as the coefficient.
