If a circle has a radius of three and a central angle of 20 what is the length of the arc

Answer 1

I assume the figure of 20 is actually 20°, which you did not state in the problem. You also need to state the units of the radius.

First, convert degrees to radians.

θ = (20°)(π/180°) = ? radians

The arc length s, with θ in radians, is

s = rθ = (3 units) (20°)(π/180°)

SImplify and finish from here.
