How to Calculate an Arc's Radius
At least two values must be known in order to calculate the radius of an arc. The chord is the distance from one endpoint of the arc to the other. The arc height is the distance from the chord's midpoint to the highest point on the arc. Once these are...
. Using the intersecting chords theorem (also known as power of a point or
secant tangent theorem) it is possible to calculate the ...
To calculate the radius. Given an arc or segment with known width and height:
Segment of a circle. A horizontal base line with an arc on the top. The formula for
Calculates the radius of an arc when the width and height of the arc are given.
The length of the arc and the angle subtended by the arc (not shown in figure)
This calculator calculates for the radius, length, width or chord, height or sagitta,
apothem, angle, and area of an arc or circle segment given any two inputs.
Geometry calculator solving for circle radius given arc length and central angle.
Purpose: To determine the linear footage (arc length) for a specific curved
application. For example, the calculator below can help you answer these
central angle calculator, arc length calculator, radius calculator, trigonometry.
Where (for brevity) it says 'radius', 'arc' and so on, it should, more correctly, ... A
problem not dealt with by this calculator is where the length of the chord (c) and ...
