The radius of the circle = 10 cm.
Chord PQ subtends an angle = 60 degrees at the centre.
PQO is an equilateral triangle, O being the centre of the circle.
Area of minor segment = θ/360 x π r2 – 1/2 r2 sinθ
= 60/360 x 22/7 x 10 x 10 – 1/2 x 10 x 10 x √3/2
= 9.03
Area of circle = πr2 = 22/7 x 10 x 10 = 314 (approx.)
Area of minor segment = Area of circle – Area of minor segment
= 314 – 9.03
= 304.97 cm2 (approx.)
