Upendo Junior School is designing a circular flag with a special sector symbol on it. The sector covers an angle of 120° at the centre and has an area of 150 cm².
Given:
Area of sector = 150 cm²
Central Angle (θ) = 120°
π = 3.142
Formula:
Area of sector = (θ/360°) × πr²
Therefore: r = √[(Area × 360°)/(θ × π)]
Find the radius of the circular flag in centimetres to 2 decimal places.
