Statement Problem: Find the radian measure of the central angle given the radius r and the arc-length s transcribed by the angle.
Solution:
You can also use the radius of the circle and the arc length to find the central angle. The central angle is given as;
[tex]\begin{gathered} \theta=s\div r \\ \text{Where s=arc length, r = radius} \end{gathered}[/tex]Given the radius and arc length as;
[tex]r=32cm,s=30cm[/tex][tex]\begin{gathered} \theta=\frac{32}{30} \\ \theta=1.0667rad \end{gathered}[/tex]
