Answer:
The wire is about <u>18.44</u> feet long.
Step-by-step explanation:
From the question:
<em>The wire is √340 feet long.</em>
This implies that the length of the wire is √340 feet.
Converting the value of this length (√340) to decimal gives;
√340 = 18.439
Now, let's convert 18.439 to the nearest hundredth of a foot.
18.439 ≅ 18.44
Therefore, the length of the wire to the nearest hundredth of a foot is 18.44 feet.
In other words, the wire is about <u>18.44</u> feet long.
