What do you need to remember for the exam, and what is given in the formulae booklet?

For C1, the only information given in the Formulae Booklet is:

**Mensuration**

Surface area of a sphere = 4лr^{2}

Area of curved surface of cone = лr x slant height

**Arithmetic series**

u_{n} = a + (n – 1)d

S_{n} = ½ n(a + l) = ½ n[2a + (n – 1)d]

Everything else you need to remember!
