Consider the following for the next two (02) items that follow : A chord of a circle of radius 2.1 cm subtends an angle of 120° at the centre. (take π = 22/7 and √3 = 1.732). What is the approximate area of major segment of the circle ?
Elementary MathematicsCircles
- A10.05 cm²
- B10.15 cm²
- C11.05 cm²
- D11.15 cm²
Explanation
The major segment is the circle minus the minor segment: π(2.1)² − 2.71 = 13.86 − 2.71 = 11.15 cm². This is option (d).
