Step-by-step explanation:
as not clear whether its a solid cylinder or a hollow cylinder,
assuming it to be solid cylinder
so tsa of solid cylinder = 2 * pie * r * (r + h)
= 2 * 22/7 * 14(14 + 120)
= 44/7 * 14(134) = 11792 cm²
area covered by wire = pie * r² = 22/7 * 0.25² = 0.196
legth required = 11792 / 0.196 = 60163 cm approx or 601.63 m
