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 m

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.

What is the difference between the predicted value and the actual value

Parallelogram efgh is a rectangle. he = 6, and fe = 8. find ge: and find fj:
