Calculate the area of a sector using the radius of an arc and the angle of rotation. This area uses units of degrees for the angle and any unit of distance for the radius.
Area of a sector formula
The area of a sector or arc can be calculated with the following formula:
Area = Pi*r^2*angle/360
- Where PI is approximately 3.14519
- r is the radius of the arc/sector
- angle is the degrees of rotation of that arc/sector
