Arc Length of a Circle Formula

An arc is a particular portion of the circumference of the circle cut into an arc, just like a cake piece. The Arc Length of a Circle is the length of circumference of the arc. It is denoted by the symbol "s". The formula to measure Arc length is, 2πR(C/360), where R is the radius of the circle, C is the central angle of the arc in degrees.


Arc Length of a Circle (S) = 2 x π x r (central angle/ 360)


r - Radius of arc
