Arc length is the distance between two points along a section of a curve . Determining the length of an irregular arc segment by approximating the arc segment as connected (straight) line segments is also called curve rectification. For a rectifiable curve these approximations don't get arbitrarily large (so the curve has a finite length).
In mathematics, an arc is defined as a portion of the boundary of a circle or a curve. It can also be referred to as an open curve. The boundary of a circle is the perimeter or the distance around a circle, also known as the circumference. So, the arc is the distance between any two points traced along its circumference.
Arc length ℓ 2 is k times as long as arc length ℓ 1 . Even though ℓ 1 and ℓ 2 measure curves, they change by the same scale factor as straight segments like the radius do!

Arc Length (Calculus) Using Calculus to find the length of a curve. (Please read about Derivatives and Integrals first) Imagine we want to find the length of a curve between two points. And the curve is smooth (the derivative is continuous ).
Arc length = θ/360 of 2πr = θ/360 × 2πr = rθ × π/180. This is the arc length formula when the angle is in degrees. The length of an arc can be calculated using different formulas, based on the unit of the central angle of the arc.
