A segment is the section between a chord and an arc. It is essentially a sector with the triangle cut out, so we need to use our knowledge of triangles here as well. To calculate the area of a ...

To calculate the sector area, first calculate what fraction of a full turn the angle is. The formula to calculate the sector area is: \(\text{Sector area} = \frac{\text{angle}}{360} \times \pi r^2 ...
