Explanation Given: Semicircle of radius r when r =1, h = 1 2 . r =1, h = 1 2 Formula used: M x = ∬ R y d y d x M y = ∬ R x d y d x x ¯ = M y A , y ¯ = M x A Calculation: From figure we take chord of circle as a and angle is theta θ 2 = r sin ( θ 2 ) ∴ sin ( θ 2 ) = a 2 r ...... ( 1 ) θ = 2 sin − 1 ( a 2 r ) ....... ( 2 ) ∴ r = a 2 sin ( θ 2 ) .......... ( 3 ) Now we will find the value of a and h in order to find area (A) h = r cos ( θ 2 ) ........ ( 4 ) = a cos ( θ 2 ) 2 sin ( θ 2 ) ....... [ From ( 3 ) ] = a 2 cot ( θ 2 ) = a 2 cos e c 2 ( θ 2 ) − 1 = a 2 4 r 2 a 2 − 1 = 1 2 4 r 2 − a 2 Now find a a 2 = r sin ( θ 2 ) a = 2 r sin ( θ 2 ) = 2 h cos ( θ 2 ) sin ( θ 2 ) ...... [ From ( 4 ) ] = 2 h tan ( θ 2 ) = 2 h sec 2 ( θ 2 ) − 1 = 2 h r 2 h 2 − 1 a = 2 r 2 − h 2 ....... ( 5 ) Therefore Area = Area of sector – Area of traingle A = 1 2 r 2 θ − 1 2 a h = 1 2 r 2 2 sin − 1 ( a 2 r ) − 1 2 h 2 r 2 − h 2 ...... [ From ( 2 ) and ( 5 ) ] = r 2 sin − 1 ( 2 r 2 − h 2 2 r ) − h r 2 − h 2 ...
