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.

<h2>Answer:</h2>
The solution of the inequality is:
We are given a inequality in terms of variable x as:
Now we are asked to find the solution of the inequality i.e. we are asked to find the possible values of x such that the inequality holds true.
We may simplify this inequality as follows:
On using the distributive property of multiplication in the left hand side of the inequality we have:
The solution is:
