Step-by-Step Guide To Calculate The Area Of A Sector Of A Circle - The central angle is the angle subtended at the center of the circle by two radii. Sectors can generally be classified into two types:
The central angle is the angle subtended at the center of the circle by two radii.
No, the central angle must be less than or equal to 360°.
It’s usually given or can be calculated based on the problem context.
Both formulas are straightforward and easy to apply once you understand the components involved.
