The Sun has a radius of 6.955×105 km and a mass of 1.989×1030 kg. What is the density of the Sun?

Answer 1

Density is given as mass/volume.

You are given the mass of 1.989x10³⁰ kg.

You can calculate the volume assuming a perfect sphere with a radius of 6.955x10⁵ km using V = 4/3πr³

Then divide the mass by the calculated volume to get density.
