Does anybody know how R³/3.98x10^14 = (2360448/2π)² equal to 1.411332x10^11

Answer 1

I don't have the foggiest idea.

my calculator says:
(2360448/(2π))² = 1.4113318 x 10^11 , (notice the change in the division by 2π)

don't know how the R³/3.98x10^14 fits in

Answer 2

Looks like Kepler's 3rd law, where you are trying to find the semi-major axis of the orbit.

R = 3.83*10^8

Looks like 1 AU in km
