On the unit circle, if s is the length of the arc subtended by a central angle θ, measured in radians, then s = θ.

6 0

<span>a. True The question is pretty much the entire definition of a radian. For an unit circle, its entire circumference is 2Ď€ and the entire circle has 2Ď€ radians. A quarter circle, or 90Â°, or Ď€/2 radians, have 1/4th of the circumference. And 2Ď€/4 is Ď€/2. This natural relationship is WHY higher mathematics uses radians for the measurement of angles rather than arbitrary units such as degrees.</span>
