The radius of Jupiter is 11 times the radius of the Earth. Calculate the ratio of the volumes of Jupiter and the Earth. How many Earths can Jupiter accommodate?
Each point: 1 Mark
1. Planets are spherical. Volume of sphere =43πr3
2. Ratio of volume of Jupiter to earth =43π(11r)343π(r)3=13311
3. So 1331 Earths can actually fit in Jupiter.
