In a circle with a radius of 6ft,an arc is intercepted by a central angle of 3π/2 radians.

Vlada [557]

$\bf \textit{arc's length}\\\\
s=r\theta ~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\[-0.5em]
\hrulefill\\
r=6\\
\theta = \frac{3\pi }{2}
\end{cases}\implies s=6\cdot \cfrac{3\pi }{2}\implies s=9\pi$
