Surface Area and Volume

Hi Hamish. I have included a big range of questions - you could almost treat it as practice for an exam and then I can give you a "mark" and go through it with you next session. Sit down with the formulas for these in front of you:

Surface Area

Volume

Area

Diameter

For each questions, be really clear if you are using Surface Area or Volume befre you start. Then use the example I text to mum as a guide for how you should be showing your working out. Each bit of working out using a formula and it can be really useful to write in different colurs or keep the working separate.

For each question, be really careful with what it is asking you to find and that will be what you are solving for in your final equation.

Some questions might also diurect you to use certain values for pi, or you might be best leaving pi as a symbol like in our sessions today.
