Question

Find the length s of the circular arc. (Assume r = 4 and θ = 118°.)

s = ???

Answer 1

Write down the formula for the circumference of a circle.

Realize that there are 360° in a full circle, so the length of a circular arc of 118° will just be 118/360 of the length of the circumference. _
