There are 2pi radians in a circle, and the sector has angle pi/12. therefore there are 24 such sectors in the complete circle.

2pi radians = 360 degrees is valid for all circles.

The question tells you that the specific sector ,mentioned has angular measure pi/12 radians, so that is just for this question
