Yes, you are right about r, sure. :)
Thank you for the correction.

You can start with Wikipedia.
It's not a theoretical calculation but rather models based on actual measurements. Or calculations based on models of the Earth's structure (based on actual seismic measurements and maybe other things I don't know about)

Guys, i think i've got it!
someone told me that the acceleration due to gravity = 9.81

It's important to know the units as well.

g = 9.81 m/s2

m/s2 is meters per second per second

in imperial units, g = 32.2 ft/s2, which is feet per second per second
