Does anyone know an easier way of memorizing the circle radians? Having a hard time figuring out how to study for that.

Explanation:

I find it easiest to remember one or two facts and use those to figure others when needed. The primary fact I remember is

  π radians = 180°

From this, you can determine ...

  360° = 2π radians

  90° = π/2 radians

  60° = π/3 radians

  45° = π/4 radians

  30° = π/6 radians

The other angles on your chart are multiples of 30° or 45°, so will be corresponding multiples of π/6 or π/4 radians, respectively.
