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.

SIX ends of tanks     6 * pi * .7      m2                           ( . 7 is the radius)

Three tank outsides   3 * pi * 1.4 * 1.9      m2               Add these together then divide by   5  m^2 / tin   (the paint coverage )
