Web9 Feb 2024 · The arc length formula is used to find the length of an arc of a circle; ℓ = θr ℓ = θ r, where θ θ is in radian. The circle’s circumference is C = 2πr C = 2 π r, as the centre angle is 2π 2 π. Correspondingly, when the centre angle is θ θ, the arc, which is a part of the circumference, is calculated as; ℓ = 2π × θ 2πr ...
