The volume of the copper wire is 226.080 cm³ and the mass of the wire is 2,012.112 g/cm³.
Given that, the length of copper wire=200 m=200000 mm and the diameter of the copper wire=1.2 mm.
We need to find the volume of the copper wire.
<h3>What is the formula to find the volume of the cylinder?</h3>
The formula to find the volume of a cylinder is πr²h.
Now, the volume of the copper wire=πr²h=
mm³=226.080 cm³
If the density of copper is 8.9 g/cm³, find the mass of the wire.
We know that
.
⇒8.9 g/cm³=
⇒Mass=2,012.112 g/cm³
Therefore, the volume of the copper wire is 226.080 cm³ and the mass of the wire is 2,012.112 g/cm³.
