Q:
What is the approximate length of the arc su tended by an angle 4pie/3 radians on a circle with a radius of 6.00 meters?
Accepted Solution
A:
[tex]\bf \textit{arc's length}\\\\ s=r\theta \quad \begin{cases} r=radius\\ \theta =angle~in\\ \qquad radians\\ ------\\ r=6\\ \theta =\frac{4\pi }{3} \end{cases}\implies s=6\cdot \cfrac{4\pi }{3}\implies s=8\pi [/tex]
