Take Earth to be a perfect sphere with radius 6370 km. Take Jupiter to be a perfect sphere with radius 69,900 km. Take the Sun to be a perfect sphere with radius 6,95,700 km. Compute approximately: (i) the ratio of the volume of Jupiter to the volume of the Earth; (ii) the ratio of the volume of the Sun to the volume of the Earth. (Calculator can be used.)

Volume ratio equals the cube of radius ratio. (i) Jupiter to Earth: (69,900/6,370)³ ≈ 1321. (ii) Sun to Earth: (6,95,700/6,370)³ ≈ 1,303,000.

    1. Since sphere volume is proportional to r³, the volume ratio between two spheres equals the cube of the ratio of their radii. (i) Ratio of Jupiter to Earth is (69,900/6,370)³ ≈ 1321 : 1. (ii) Ratio of Sun to Earth is (6,95,700/6,370)³ ≈ 1,303,000 : 1.
