Question

How many radians are in a full rotation around a circle, or 360°?

Answer 1

There are 2 radians in a full circle. A Radian "cuts out" a length of a circle's circumference equal to the radius

Answer 2

2pi also works because you start at 0 the pi/2 , pi , 3pi/2 then back to 0 but you would say 2pi
