Tim has to cover 3 tanks completely with paint. Each tank is in the shape of a cylinder with a top and a bottom. The tank has a diameter of 1.4 metres and a height of 1.9 m. A tin of paint covers 5 m2

Find the total surface area of the 3 tanks and state how many tins of paint Tim will need to buy. You must show your working.
