Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. Radius r Arc Length s 35 kilometers 75 kilometers

Question

Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s.

Radius r		Arc Length s
35 kilometers		75 kilometers

Answer 1

To find the radian measure, all you have to do is divide the arc length by the radius.

Θ=s/r

=75/35

=15/7

≈2.15
