Question

Find the length of the gray arc in terms of pi

Answer 1

Given

a: angle

a = 60

r: radius

r = 3

Procedure

The length of an arc depends on the radius of a circle and the central angle θ

`\begin{gathered} s=\theta r \\ s=(1)/(3)\pi\cdot3 \\ s=\pi \end{gathered}`

The answer would be s = pi
