Exercise 15.3 Solutions
1. AB is a chord of a circle with centre O and radius 4cm. AB is length 4cm and divides circle into two segments. Find the area of minor segment
Solution
2. A chord of circle of radius 14 cm makes a right angle at the centre. Find the areas of minor and major segments of the circle.
Solution
3. A chord 10 cm long is drawn in a circle whose radius is 5√2 cm. Find the area of both segments
Solution
Given radius = r = 5√2 cm = OA = OB
Length of chord AB = 10 cm
Solution
5. AB is the diameter of a circle, centre O. C is a point on the circumference such that ∠COB = Î¸. The area of the minor segment cutoff by AC is equal to twice the area of sector BOC. Prove that sinÎ¸/2 cosÎ¸/2 = Ï€(1/2  Î¸/120°)
Solution
6. A chord of a circle subtends an angle Î¸ at the centre of circle. The area of the minor segment cut off by the chord is one eighth of the area of circle. Prove that 8 sinÎ¸/2. cosÎ¸/2
Ï€ = Ï€Î¸/45
Ï€ = Ï€Î¸/45
