The length of the arc in terms π is (2.44π)in
An arc is a cut out part of a circumference of a circle. The circumference of circle is the outer body of the circle.
The length of an arc is calculated as by multiplying the ratio of the angle substended by the arc and 360 with circumference of a circle.
l = x/360 × 2πr
where x is the angle substended
l = 110/360 × 2 × π × 4
l = 880π/360
l = 2.44π
Therefore, the length of the arc is 2.44π
