Question

What is the arc length of the subtending arc for an angle of 60° on a circle of radius 3?

Answer 1

use this formula
\[s=\theta r \]
where s = arc
theta = degrees
r = radius

Answer 2

and you also have to convert 60 degrees into radians

Answer 3

use \[\frac{\pi}{180} \] to convert from degrees to radians
multiply 60 by \[\frac{\pi}{180} \]
