Practical Example

Suppose you have a circle with a radius of 10 cm and an angle of 60 degrees. Here’s how to calculate the arc length:

1. Enter 10 in the radius field.
2. Enter 60 in the angle field.
3. Select Degrees from the angle unit dropdown.
4. Click Calculate.

Results:

• Arc Length = 10×(60×π/180)≈10.47210 × (60 × π / 180) ≈ 10.47210×(60×π/180)≈10.472 cm
• Angle in Radians = 60×π/180≈1.04760 × π / 180 ≈ 1.04760×π/180≈1.047 rad

This quick calculation can be invaluable for designing circular segments, crafting projects, or solving geometry problems.
