Kepler-36b and Kepler-36c are two highly close planets orbiting around their parent star, Kepler-36. Kepler-36b has an orbital period of 13.9 days and its mean orbital radius from Kepler-36 is 0.1153 AU. The orbital period for Kepler-36c is 16.2 days. Presume that the two planets have no effect on one another. Calculate Kepler-36c's orbital distance (r_Kepler-36c ) in the atmospheric unit (AU) without using the mass of the parent star.
