Question

Find the length of the arc. 8 m 315°

Answer 1

$s = 44.0\:\text{m}$

Step-by-step explanation:

First convert the angle into radian measure:

$315°×\left(\dfrac{\pi}{180°}\right) = 5.50\:\text{rad}$

The arc length s is given by

$s = r\theta = (8\:\text{m})(5.50\:\text{rad}) = 44.0\:\text{m}$
