## Exam Style Question## Worked solutions to typical exam type questions that you can reveal gradually |

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

The volume of the Moon is \(2.2 \times 10^{10}\) km^{3}

The volume of the Saturn is \(8.3 \times 10^{14}\) km^{3}

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.

$$v=\frac43\pi r^3$$Give your answer to 2 significant figures.

The worked solutions to these exam-style questions are only available to those who have a Transum Subscription. Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves. This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures. A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience. |
