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. Class 9 Ganita Manjari part 2 Chapter 14 end of chapter exercise Solutions Class 9 Ganita Manjari Part II ...
