Question
The radian measure of an angle is defined as the ratio of which two quantities?
Correct Answer
Option B is the correct answer.
Detailed Explanation
By definition, the angle in radians, θ, is given by the formula θ = s/r, where s is the arc length along a circle and r is the radius of that circle. It is the ratio of arc length to radius.
Hint
Consider the relationship between the length of a circular arc and the radius of the circle that defines the angle.
