Exam-Style Question on Mensuration
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 533. This question is similar to one that appeared on a GCSE Higher paper in 2019. The use of a calculator is allowed.
Babatunde has to paint four containers.
Each container is in the shape of a cylinder with a diameter of 1.2m and a length of 3.2m.
How many tins of paint will Babatunde need to buy to completely cover each of the four containers if each tin of paint covers 6m2?
You must show all of your working.
[The surface area of a cylinder of radius \(r\) and height (or length) \(h\) is \(2\pi rh + 2\pi r^2\)]
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.
