How many radii fit around a circle? #tauday #tau

In this short, we investigate how many radii of a circle would fit if you lay them in arcs around a circle. The method of laying a single radius around the circle creates an angle subtended by that arc - that angle is known as 1 radian. So in this video we see that there are more than 6 radians and less than 7 radians in a circle. The full measurement is actually around 6.28 and is the constant 2*Pi. #short #math #manim #radian #circle #radius #tauday #tau
