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 = 𝟏/πŸ” Γ— 𝝅𝒓^𝟐 Putting formula 𝜽/(πŸ‘πŸ”πŸŽΒ°) Γ— 𝝅𝒓^𝟐 = 𝟏/πŸ” Γ— 𝝅𝒓^𝟐 πœƒ/(360Β°) = 1/6 ΞΈ = (360Β° )/6 ΞΈ = 60Β° So, the correct answer is (b)
