🧮 How to Use the Arc Distance Calculator (Step-by-Step)
Follow these simple steps to calculate arc distance:
Step 1️⃣ – Enter the Circle Radius
Input the radius of the circle in your preferred units (meters, centimeters, inches, etc.).
Example:
Radius = 10 meters
Step 2️⃣ – Enter the Central Angle
Provide the angle that defines the arc. You can use degrees or radians depending on your preference.
Example:
Angle = 60°
Step 3️⃣ – Select Units
Choose whether your angle is in degrees or radians.
Example:
Angle Unit = Degrees
Step 4️⃣ – Click “Calculate”
The calculator will instantly display:
- Arc length
- Optional: fraction of the circle’s circumference
- Conversion between degrees and radians
📊 Example: Calculating Arc Distance
| Details | Value |
|---|---|
| Circle Radius | 10 meters |
| Central Angle | 60° |
| Arc Length | 10.47 meters |
| Fraction of Circle | 1/6 of circumference |
How it works:
The formula used by the calculator is: Arc Length=r×θ\text{Arc Length} = r \times \thetaArc Length=r×θ
Where:
- rrr = radius of the circle
- θ\thetaθ = angle in radians (if angle is in degrees, convert using θ×π/180\theta \times \pi / 180θ×π/180)
In this example: 10×(60×π/180)=10×π/3≈10.47 meters10 \times (60 \times \pi / 180) = 10 \times \pi / 3 \approx 10.47 \text{ meters}10×(60×π/180)=10×π/3≈10.47 meters
