WebTo calculate the length of the arc we use different formulas based on the unit of the central angle (degrees or radians). For a circle, the arc length formula is θ times the radius of a circle. The formulas are: Arc Length = θ × r (used for radians) Arc Length = θ × (π/180) × r (used for degrees) Where, L = Length of an Arc; θ = Central ... WebFormula for S = r θ. The picture below illustrates the relationship between the radius, and the central angle in radians. The formula is S = r θ where s represents the arc length, S = r θ represents the central angle in radians and r is the length of the radius.
