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

1. Always use consistent units for radius and arc length
2. Double-check your angle measurement (degrees vs. radians)
3. For very large or small circles, consider using more decimal places in your calculations
