Question

The radius of Jupiter is 11 times the radius of earth. Calculate the ratio of the volume of Jupiter and earth. How many times earth can Jupiter accommodate?

Answer 1

1. Planets are spherical. Volume of sphere = $\frac{4}{3}\pi r^3$

2. Ratio of volume of Jupiter to earth =$\frac{\frac{4}{3}\pi (11r{)}^3}{\frac{4}{3}\pi r^3}=1331$

3. So 1331 Earths can actually fit in Jupiter.
