## Essential University Physics: Volume 1 (3rd Edition)

We know that The volume of the Sun is given as $V_S=\frac{4}{3}\pi R^3_S$ and the volume of Earth is given as $V_E=\frac{4}{3}\pi R^3_E$ Now we can find the ratio $\frac{V_S}{V_E}=\frac{\frac{4}{3}\pi R^3_S}{\frac{4}{3}\pi R^3_E}$ $\frac{V_S}{V_E}=(\frac{R_S}{R_E})^3$ We plug in the known values to obtain: $\frac{V_S}{V_E}=(\frac{6.96\times 10^8}{6.37\times 10^6})^3$ $\frac{V_S}{V_E}=1.30\times 10^6$
