Radius, r = 4 cm

Height, h = 10 cm


Volume = 1/3πr2

(π x 42 x 10) ÷ 3

Volume = 167.6 cm3 (1 dp)


Note: It is important to get the order correct in these calculations!

Did you spot the brackets around most of the equation?

We need to do all the multiplication in the brackets before dividing by 3.
