Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

The height of the tank

$h=$ Unnamed gap m

Advice

This section draws on the skills learnt the previous parts of the 'Differentiation' series of questions, and some geometry knowledge.

The hint under the steps should be all the extra information you need.

Give a worked solution to the whole question.
