Answer:
Step-by-step explanation:
The volume of a sphere is defined to be:
[tex]V=\frac{4}{3} \pi r^3[/tex]
Plug in the values for both planets. The radii of the planets was already given:
[tex]V_e=\frac{4}{3} \pi (6378.1)^3[/tex]
[tex]V_e=1.1*10^1^2kg^3[/tex]
[tex]V_m=\frac{4}{3} \pi (3390.0)^3[/tex]
[tex]V_m=1.6*10^1^1kg^3[/tex]
Earth is this many times larger than Mars:
[tex]\frac{V_e}{V_m} =\frac{1.1*10^1^2}{1.6*10^1^1} =6.9[/tex]
