The copper wire

The copper wire bundle with a diameter of 2.8mm has a weight of 5kg. How many meters of wire is bundled if 1m3 of copper weighs 8930kg?

Correct result:

l =  90.9 m

Solution:

D=2.8 mm m=5 kg ρ=8930 kg/m3  r=D/2=2.8/2=75=1.4 mm r2=r m=r/1000  m=1.4/1000  m=0.0014 m m S=π r22=3.1416 0.001426.1575106 m2  m=ρV m=ρSl  l=mρ S l=mρ π r22=58930 3.1416 0.00142=90.9 m
