Question

Calculate the volume of the Earth (V_E) and the Sun (V_s) and compare them to each other by dividing the volume of the Sun by the volume of the Earth. Express the result in words.

Answer 1

Radius of the Sun: 695,700 km 

Radius of the Earth: 6378 km

Volume of a sphere = 4/3πr³

Volume of the Sun V_s = (4 x 3.14 x (695, 700)³)/3

V_S = 1.4097 × 10¹⁸ km³

Volume of the Earth V_E = (4 x 3.14 x (6378)³)/3

V_E = 1.0862 × 10¹² km³

V_S/V_E = (1.4097 x 10¹⁸)/(1.0862 x 10¹²) = 1.297 x 10⁶ (dimensionless)

V_s = 1.297 x 10⁶V_E

The Volume of the Sun is one million two hundred ninety seven times larger than the volume of the Earth.
