Question

Find the length of a circular arc subtended by an angle of π/12 rad if the radius of the circle is 36 cm.

[please draw a picture to say what it means as well as explain how to solve]

Answer 1

\[s=r\theta\]when r is the radius and theta is the angle given in radians. Just plug in the numbers for the arc length s.

Answer 2

\[\huge{s=r\theta}\]where s is the arc length, r is the radius of the circle, and theta is the angle given in radians.
Just plug in the numbers given for the radius and angle and you will get the arc length.
