If $\"\"$ (in radians) is a central angle in a circle with radius $\"\"$ , then the length of the arc cut off by $\"\"$ is $\"\"$ .

$\"\"$

Find arc length.

Central angle $\"\"$ and radius $\"\"$ mm.

First convert the angle into radians.

$\"\"$

Consider $\"\"$ .

Substitute the values of $\"\"$ and $\"\"$ mm in above formula.

$\"\"$

Thus, the length of the arc is $\"\"$ mm.

$\"\"$

The length of the arc is $\"\"$ mm.
