    You do know that you are entitled to request maths tables in the exam? Page 6 & 7 are where they all are.

    Plus, what objects do you want the area and volume for?

    just buy a copy of the tables in you local book shop!! there only like a euro! but anyway, the main ones that arent in it are the volume of a hemisphere and the trig formule for getting area :) not much, plus just half the sphere formule for volume and you have the hemisphere formule!

    the ones not in the tables are:

    length of arc

    area of arc

    surface area of a cube

    total surface area of a cylinder

    total surface area of cone

    vol. of hemisphere

    surface area of hemisphere

    perimeter of a rectangle

    I think the length of an arc and the area of a sector are in the tables.

    the area one is but in an unusual radians format, while the easier alternative of
    angle divided by 360 x (pie (r)squared)

    length is not there

    Nope, I'm looking at the formula for the length of the arc of a circle with radius r right now on page 6 of the tables, top of the page.
