Question

what is a segment a sector and an arc in a circle ??? please
tell me every detail on these topics

Manish Bharti · Accepted Answer

Sector- The portion (or part) of the circular region enclosed by two radii and the corresponding arc is called a sector of the circle

Area of the sector of angle $θ$ $= \frac{θ}{360} \times π r^{2}$ Length of an arc of a sector of angle $θ$ $= \frac{θ}{360} \times 2 π r$ Segment- the portion (or part) of the circular region enclosed between a chord and the corresponding arc is called a segment of the circle

Area of segment PAB = Area of Sector OAPB - Area of triangle OAB $= \frac{θ}{360} \times π r^{2} - A r e a o f Δ O A B$ Arc- acircular arc is a segment of the circumference of a circle

Length of an arc of a sector of angle $θ$ $= \frac{θ}{360} \times 2 π r$
