## How to Calculate Perimeter Of Segment Of Circle

### Example: What is the perimeter of segment of circle with radius = 22 units and angle = 54 units?

As;

perimeter of segment of circle = (π*radius*angle/180+2*radius*Math.sin(angle/720)

By substituting the above given data in the previous function;

(i.e.) = (π*22*54/180+2*22*Math.sin(54/720)
