The Chord to Radius Calculator is a tool that computes the radius of a circle given the chord length and the sagitta (the perpendicular distance from the midpoint of the chord to the arc).
Formula
The formula to calculate the radius is:
\[ R = \frac{L^2}{8S} + \frac{S}{2} \]
Where:
- L is the chord length.
- S is the sagitta.
Example Calculation
For a chord length (L) of 10 units and a sagitta (S) of 2 units:
\[ R = \frac{10^2}{8 \times 2} + \frac{2}{2} = \frac{100}{16} + 1 = 6.25 + 1 = 7.25 \text{ units} \]
Application
This calculation is used in geometry, construction, and engineering to determine the radius of curved surfaces, arcs, and circular segments.
