Question

For a circle of radius 3 feet, find the arc length s subtended by a central angle of 57 degrees. the wanted it in radians but I keep getting the wrong answer.

Answer 1

To convert degrees to radians you multiply it by pi/180

Answer 2

Then multiply that with the radius to get the arc length.

Answer 3

\[\theta=\frac{ l }{ r },l=r \theta \]
where l is the length of arc.
r=radius of circle
\[\theta=\angle~\in~radians.\]
