The result will show you the arc length instantly!
The Arc Length Formula
The formula used in our calculator is:
Arc Length = (θ / 360°) × 2πr
Where:
- θ (theta) is the central angle in degrees
- r is the radius of the circle
- π (pi) is approximately 3.14159
Practical Applications of Arc Length
Understanding arc length has numerous practical uses:
- Architecture: Designing arched structures
- Engineering: Calculating material needed for curved components
- Navigation: Determining distances on curved paths
- Physics: Analyzing circular motion
Tips for Accurate Measurements
- Always use consistent units for radius and arc length
- Double-check your angle measurement (degrees vs. radians)
- For very large or small circles, consider using more decimal places in your calculations
Frequently Asked Questions
Q: Can this calculator work with radians?
