Diameter of wire = 6 mm
Radius of wire = 3 mm
Radius of cylinder = 49 / 2 cm
Height of cylinder = 15 cm = 150 mm
______________________________
Number of times the wire is wrapped = Height of cylinder / Diameter of wire
= 150 / 6
= 25
______________________________
Length of wire = Circumference of Base of cylinder × 25
= (2 × 22 × 49 / 2 × 7 ) × 25
= 22 × 7 × 25
= 3850 cm
= 38.5 m
______________________________
Volume of wire = pi × R^2 × Length
= 22 × 3 × 3 × 38500 / 7
= 22 × 9 × 5500 mm^3
= 1089000 mm^3
= 1089 cm^3

Weight = 1089 × 9 g
= 9801 g
= 9.801 kg
