Question

Given a circle with a radius of 2, which is the length of an arc measuring 75 degrees?

Answer 1

$\bf \textit{arc's length}\\\\ s=\cfrac{r\theta\pi }{180}\qquad \begin{cases} \theta=\textit{angle in degrees}\\ r=radius\\ ---------\\ r=2\\ \theta=75 \end{cases}\implies s=\cfrac{2\cdot 75\cdot \pi }{180}$
