Who help me is a genius

Answer 1

`\bf \textit{arc's length}\\\\ s=r\theta ~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad radians\\ ------\\ r=6\\ s =(3\pi )/(4) \end{cases}\implies \cfrac{3\pi }{4}=6\theta \implies \cfrac{3\pi }{24}=\theta \\\\\\ \stackrel{simplified}{\cfrac{\pi }{8}=\theta }`
