So 360 degrees corresponds to an arc length C 2pR. Where th equals the measure of the central angle that intercepts the arc and r equals the length of the radius. A full 360 degree angle has an associated arc length equal to the circumference C.
1 degree corresponds to an arc length.
L 45360 2 227 4. The Radius of a Sector Formula calculates the radius by dividing the length of an arc by the value of circumference of p. The length of the same sector th360 2pr. If you need to find the area of a sector using the arc length that distance will be given to you.
