Radius Unwrapper v2.0

Author:
Ted Coe
Topic:
Angles, Circle
Try to imagine how you might measure the subtended arc in terms of radius lengths. Once you have taken a guess use the slider to see the unfolded length. Turn on the radius ruler to confirm your guess. Geogebra will measure the angle in terms of radians, but it will restrict the answer on the interval of zero to 2 Pi.
