Q. Which of the following radian measures is equal to 15∘? Choose 1 answer: (A) 12π radians (B) 6π radians (C) 3π radians (D) 4π radians
Identify Formula: Identify the formula to convert degrees to radians. The formula is radians=degrees×(180°π).
Convert Degrees to Radians: Convert 15 degrees into radians using the formula. By substituting 15 degrees into the formula, we get 15∘×(π/180∘)=18015π radians.
Simplify Fraction: Simplify the fraction18015π by dividing both the numerator and the denominator by their greatest common divisor, which is 15. This gives us 12π radians.
Match Radian Measure: Match the simplified radian measure to the given choices. The correct match is (A)(12π) radians.
