Area of a Circular Segment (from the Central Angle)
Calculate the area, arc length, and chord length of a circular segment using its radius and central angle.
| Area S | |
| Arc Length L | |
| Chord length c |
| \(\normalsize Arch\\ (1)\ area:\hspace{65px} S={\large\frac{1}{2}}r^{2}(\theta-\sin\theta)\\ (2)\ circular\ arc :\ L=r\theta\\ (3)\ chord :\hspace{60px} c=2r\sin{\large\frac{\theta}{2}}\\\) |
