The arc length is related to the angle and length of the radius of the circle via the equation

S=r\theta

This is a unit circle, hence, <em>r</em> = 1. The angle is given as 1.5 radians or can be written as 1.5π. Hence, the length of the intercepted arc is computed as

\begin{gathered} S=(1)(1.5\pi) \\ S=1.5\pi \end{gathered}
