Question:
The diagram shows a circle centre O and radius 6 cm. The chord PQ divides the circle into a minor segment R1 of area A1 cm2 and a major segment R2 of area A2 cm2. The chord PQ subtends an angle θ radians at O.
a. Show that A1 = 18(θ − sin θ). Given that A2 = 3A1,
b. show that sin θ = θ - π/2.
