2 Dr Seroto has a choice of two cylindrical containers (as shown below) for display purposes. A decorative label with a 1 cm overlap will be placed right around the container completely covering the curved surface only. CYLINDER-A Diameter = 30 cm Height = 30 cm CYLINDER-B The following formula may be used: Diameter = 40 cm Height = 20 cm Verily, showing ALL calculations, whether cylinder B would require less material to make the decorative labels. Curved surface area of cylinder =3.142× diameter× height, z = 3,142
