Change radius of 7.0E5 km to cm; then (4/3)*pi*r^3 = volume of star.
Change mass 1E36 kg to g.
Density = mass/volume
Post your work if you get stuck.
A star is estimated to have a mass of 1 ✕ 1036 kg. Assuming it to be a sphere of average radius 7.0 105 km, calculate the average density of the star in units of grams per cubic centimeter.
round to the correct number of significant figures.
