    so the area is 100*100 with circle in it, from the centar to the endline of the circle = 50

    the first spot is on x=50 y=100 0 degrees

    solwed it
    if half of circle is 50 in other words "hip = 50"
    pi = 3.1415926535897932384626433832795

    x = Sin(angle * ( pi / 180) ) * hip
    y = Cos(angle * ( pi / 180) ) * hip
    and i got new coordinates to use for that angle
