let the silver is in the form of cube.
a³=1
it is drawn into as wire in form of cylinder.
πr²h=1
radius = 1mm/2=0.05cm
π(0.05)²h=1
π(0.0025)h=1
πh=1/0.0025
h=400/π
h=400×7/22
h=127.27

Answer:
Ans=84
Explanation:
Diameter = 1mm
Radius=1/2 mm = 1/20 cm
A wire is a 3D shape name cylinder
So Area of cylinder = 22/7 x r x r x height
66= 22/7 x 1/20 x 1/20 x h
66 x 1400 = 11h
92400= 11h
92400/11 = h
h = 8400 cm
1 m = 100 cm
8400 cm = 84 m
So the answer is 84 meters.
