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) 90Β° (b) 60Β° (c) 45Β° (d) 30Β° Given that Area of sector = π/π Γ π π^π Putting formula π½/(πππΒ°) Γ π π^π = π/π Γ π π^π π/(360Β°) = 1/6 ΞΈ = (360Β° )/6 ΞΈ = 60Β° So, the correct answer is (b)
