The inner side of the cylindrical vessel is made of silver, and the outer side is made of copper. The height of the vessel is 36 \(cm\), the outer radius is 4.4 \(cm\), and the inner radius is 4 \(cm\). Calculate:
 
(i) the curved surface area of the vessel made by silver
 
(ii) the curved surface area of the vessel made by copper
 
(iii) the area of the ring formed between two layers of the metal on the top face
 
\([\)Use \(\pi = 3.143]\)
