Line 55:
As an example, the area is one quarter the circle when ''θ'' ~ 2.31 radians (132.3°) corresponding to a height of ~59.6% and a chord length of ~183% of the radius.{{Clarify|date=December 2021|reason= A diagram with these numbers would be a good addition to the example}}
 
=== Etc.Other properties ===
The perimeter ''p'' is the arclength plus the chord length,:
 
:<math>p=c+s=c+\theta R</math>
Proportion of the whole area of the circle:
 
As a proportion of the whole area of the disc, <math>A= \pi R^2</math>, you have
 
:<math> \frac{a}{A}= \frac{\theta - \sin \theta}{2\pi}</math>
