Acircle has a radius of 63 centimeters. what is the arc length intercepted by a central angle that measures 2π/9 radians? express the answer in terms of π .
Answers: 1
![\bf \textit{arc's length}\\\\ s=\theta r~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad radians\\[-0.5em] \hrulefill\\ r=63\\ \theta =\frac{2\pi }{9} \end{cases}\implies s=\cfrac{2\pi }{9}\cdot 63\implies s=14\pi](/tpl/images/0037/3380/b6bf1.png)
