The formula for length of an arc on a circle is given by the formula:
,
where 'r' is the radius of the circle and 'x' is the measure of the central angle of the arc.
We have to determine the value of radius 'r'.
Since,
By Cross multiplication, we get
Therefore, the radius 'r' is given by .
Option 4 is the correct answer.
