This angle measure can be in radians or degrees and we can easily convert between each with the formula p radians 180 p r a d i a n s 180. Then Angle at center Length of Arc Radius of circle. The result will be the radius.
The general formulas for calculating the arc length of a section of a circle are.
L e n g t h th 360 2 p r. This angle measure can be in radians or degrees and we can easily convert between each with the formula p radians 180 p r a d i a n s 180. Arc length formula is used to calculate the measure of the distance along the curved line making. The result will be the radius.
