Your function will be provided with the five vertices of a pentagon (p) as well as the center point (cp) and radius (r) of a circle. The pentagon will be centered about the circle. The function should return one of the following values:

0: the pentagon is completely enclosed within the circle but is not inscribed
1: the pentagon is inscribed in the circle (within ±0.02)
2: the vertices of the pentagon extend beyond the circle

Points will be rounded to the nearest hundredth. See the test cases for examples.
