The length of the circular arc is   3π cm.

Explanation of Solution

The length of the circular disc is a=rθ where the radius r and θ is the central angle.

Here, it is given that θ=π12 rad and r=36 cm.

Substitute the value θ=π12 rad and r=36 cm in the formula a=rθ.

a=rθ=π12(36)=3π

Thus, the length of the circular arc is 3π cm.
