Line 33:

:<math>s = {\theta}R</math>

The area ''<math>a''</math> of the circular segment is equal to the area of the [[circular sector]] minus the area of the triangular portion (using the double angle formula to get an equation in terms of <math>\theta</math>):

:<math>a = \tfrac{R^2}{2} \left(\theta - \sin \theta\right)</math>
