One of the end stages of stellar life is a neutron star, where matter collapses and electrons combine with protons to form neutrons. Some liken neutron stars to a single gigantic nucleus.

Calculate the radius in meters of a neutron star with a mass 3.06 x 10³⁰ kg, treating it as a giant nucleus.

Consider the mass of a nucleon 1.675 x 10^-27 kg.

Your answer should be in the form of N x 10⁴years. Enter only the number N with two decimal places, do not enter unit.
