Question

Use the arc length formula and the given information to find s.
r = 20 ft θ = 19° s = ?

Answer 1

first you need to convert \(19^\circ\) to the usual radian measure
do you know how to do that?

Answer 2

Use the arc length formula, \(S=\theta \times \frac{ \pi }{ 180 }\times r\), where \(r\) is the radius.

So with the given, find S.
\(\huge S=\ 19\times \frac{ \pi }{ 180 }\times 20\)

Answer 3

agree ;)
