Question 38 Area of a sector of a circle is 1/6 to the area of circle. Find the degree measure of its minor arc. (a) 90° (b) 60° (c) 45° (d) 30° Given that Area of sector = šŸ/šŸ” Ɨ š…š’“^šŸ Putting formula šœ½/(šŸ‘šŸ”šŸŽĀ°) Ɨ š…š’“^šŸ = šŸ/šŸ” Ɨ š…š’“^šŸ šœƒ/(360°) = 1/6 Īø = (360° )/6 Īø = 60° So, the correct answer is (b)
