Arc Length Calculator
Calculate the length of an arc using radius and angle measurements
About Arc Length Calculation
An arc length is a portion of the circumference of a circle or curve. The calculation depends on two key components:
- The radius of the circle
- The central angle that defines the arc (in degrees)
This calculator uses the formula: L = (πrθ)/180°, where:
- L = arc length
- r = radius
- θ = central angle in degrees
- π = pi (approximately 3.14159)
Common Applications
- Architecture and Construction: Calculating curved surfaces and arches
