The Chord to Radius Calculator is a valuable tool in geometry, specifically used to determine the radius of a circle given the chord length and the arc height (or sagitta). It simplifies complex calculations and is essential in various fields requiring precise circle measurements.

### Importance

Understanding the radius of a circle from its chord length and arc height is crucial for:

**Engineering**: Used in structural analysis and design where circular components are involved.**Architecture**: Essential for designing arches and curved structures.**Surveying**: Helps in accurately measuring circular boundaries and land plots.**Mathematics Education**: Aids in teaching geometric principles and circle properties.

### How to Use

Using the Chord to Radius Calculator involves these steps:

**Input Chord Length**: Enter the length of the chord that spans the arc of the circle.**Enter Arc Height**: Input the height of the arc (sagitta), which is the perpendicular distance from the chord to the circle's midpoint.**Calculate**: Click the "Calculate Radius" button to obtain the radius of the circle.

The formula used in the calculator is: Radius=H28C+C8\text{Radius} = \frac{H^2}{8C} + \frac{C}{8}Radius=8CH2+8C where HHH is the arc height and CCC is the chord length.
