Give me a Python code to find a radius r (centered at *xy*) between *rmin* and *rmax* at given the following:
Complete the below
def find_r_to_boundary_of_closedpath(inside_closedpath, xy, cos_t, sin_t, rmin=0.0, rmax=1.0, tolerence=0.01):

    ''''Find a radius r (centered at *xy*) between *rmin* and *rmax* at
    which it intersect with the path.
    inside_closedpath : function
    cx, cy : center
    cos_t, sin_t : cosine and sine for the angle
    rmin, rmax :'
