Question id: 151. This question is similar to one that appeared on a GCSE Higher paper (specimen) for 2017. The use of a calculator is allowed.

The volume of the Moon is $$2.2 \times 10^{10}$$ km3

The volume of the Saturn is $$8.3 \times 10^{14}$$ km3

How many times larger is the radius of Saturn than the radius of the Moon?

Assume that Saturn and the Moon are both spheres and that the volume $$v$$ of a sphere with radius $$r$$ is given by the following formula.

$$v=\frac43\pi r^3$$
