AB is a chord of a circle with centre O and radius 4cm. AB is of length 4cm and divides the circle into two segments. Find the area of the minor segment.

Question

Philoid · Accepted Answer

_Given,

_{Radius of circle = 4cm}

_{Length of chord = 4cm}

(Hence it makes an equilateral triangle at centre, in which all angle must be = 60°)

Area of sector =

Area of ∆OAB =

Area of minor segment = area of sector – area of ∆OAB
