If a circular arc of the given length s subtends the central angle θ on a circle, find the radius of the circle.
s = 5 cm, θ = 2

Respuesta :

[tex]\bf s=r\theta\qquad \begin{cases} s=\textit{arc's length}\\ r=radius\\ \theta=\textit{central angle in radians}\\ \qquad \textit{made/subtended by the angle }\theta \end{cases}\implies \cfrac{s}{\theta}=r[/tex]
