Answer»

? DIAMETER of the vessel = 14 CM

∴ RADIUS = 7 cm;

We need to find out the surface area of the spherical vessel;

Surface area of spherical vessel = 4πr²

⇒ 4 × 22/7 × 7²

⇒ 616 cm²

? The cost of PAINTING the spherical vessel is Rs. 8008;

∴ Cost of painting PER square centimetre = 8008/616 = Rs. 13
