[139] Around a circular lake, whose radius measures 1 km, there is a bike path. Due to frequent bicycle thefts, the city hall plans to allocate police officers in strategic positions to patrol this bike path, in order to make it fully protected.

The figure illustrates a point P on the bike path, which will be protected if there is at least one police officer positioned on the dark gray area.
