Use the arc length formula and the given information to find s. Show your work for full credit ... r = 20 ft θ = 19° s = ?

Given:

r = 20 ft

Θ = 19°

s = ?

s = rΘ; where angle Θ should be measured in radians

1 degree = 0.0174533 radian

19° x 0.0174533 radians/1° = 0.3316127

s = 20ft * 0.3316127

s = 6.632254 or 6.63 ft

The arc length is 6.63 ft.
