    So for my maths exam there are questions on like finding the volume of a cuboid, circumference of a circle, area of a circle, diameter and radius.

    I just find it impossible to try and remember these because not only is it they ask for the circumference sometimes they ask for the diameter and it'll not tell you the radius etc.

    On the start of the examination papers they give you a formula sheet for the area of a trapezium and a formula for the area of a prism.

    I don't understand why they don't provide formulas for things like circles. Is it ok to write them on a sheet and bring them into the exam?

    You won't be able to take anything additional into the exam with you.
    In terms of resources for the exam, you can only use what is provided to you by the exam board.

    What I find handy sometimes is to write down the formulas on the paper as soon as the exam starts, so that just in case I forgot them they are available to me if I need to use them.

    To find the diameter if you're only given the circumference, then you just need to divide by pi.
    The diameter fits into the circumference roughly 3.14 times (or exaclty pi times)

    No you won't be able to do this. It's annoying but it's just the way it is. Sometimes they give you the formulas for certain shapes, e.g. cones, but you have to rely mostly on your own memory.

    I would recommend trying to find some memory aids for learning formulas, for example, (C)herry (PI)es a(R)e (D)elicious
    [ Circumference = Pi x Diameter (or 2xRadius - same thing) ],
    (A)pple (Pi)es a(R)e 2
    [ Area = π x r^2)

    There are lots of these kind of things for different formulas, so I recommend you look them up.
