The Radius of a Circle based on the Chord and Arc Height calculator computes the radius based on the chord length (L) and height (h).
INSTRUCTIONS: Choose units and enter the following:
Radius (r): The calculator returns the radius in meters. However, this can be automatically converted to compatible units via the pull-down menu.
The formula for the radius of a circle based on the length of a chord and the height is:
`r = L^2/(8 h) + h/2`
where:
A useful application of the math construct is in construction where the formulas computes the radius of an arch.
