I'm working on trying to determine a formula that can model the density of the sun.(adsbygoogle = window.adsbygoogle || []).push({});

density:

[tex]\rho[/tex] = m/v

the volume of a three dimensional figure is b*h

therefore: v of cylinder = Area of a circle * h (delta r = h)

v=[tex]\pi[/tex]R^{2}[tex]\Delta[/tex]r

therefore: [tex]\rho[/tex] = ([tex]\Delta[/tex]m)/([tex]\pi[/tex]R^{2}[tex]\Delta[/tex]r)

If this equation is wrong please comment.

Well in order for me to model this I need to figure out the radius of the sun; I know I can easily search for the value on the internet, but how is it actually determined?
