A pie segment of construction geometry displays the relation between the arc and the radius for a given angle. InputLength = ReferenceRadius * Pi and ArcLength = DynamicRadius * Pi * ArcAngle / 180° with constant length results in: ReferenceRadius * Pi = DynamicRadius * Pi * ArcAngle / 180° And with Pi eliminated we get: ReferenceRadius = DynamicRadius * ArcAngle / 180° or DynamicRadius  = ReferenceRadius  * 180° / ArcAngle
 * The [[Image:Bound-expression.svg|16px]] expression for the DynamicRadius value:
