Please help me find out the values used to get the answer below. I dont know which units should be placed where and what units I should convert. Please show which values to put to get the answer below.

PROBLEM 11.153
A satellite will travel indefinitely in a [nearly]
circular orbit around a planet if the normal
component of the acceleration of the satellite is
equal to g(R/r)2, where g is the acceleration of
gravity at the surface of the planet, R is the radius
of the planet, and r is the distance from the center
of the planet to the satellite.

Knowing that the diameter of the Sun is 1.39 Gm
and that the acceleration of gravity at its surface is
274 m/s² (NOTE: 28 times Earth g), determine the
radius of the orbit of the Earth around the Sun
assuming that the orbit is circular.
Consider for Earth: (v mean) orbit = 107 Mm/h.
