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 \(2\pi rh + 2\pi r^2\)]
