Explanation:

Step1: Write the formula for circumference

The formula for the circumference \(C\) of a circle is \(C=\pi d\), where \(d\) is the diameter.

Step2: Substitute the value of diameter

Given \(d = 142\) m. Substitute \(d\) into the formula: \(C=\pi\times142\).

Step3: Calculate the value

Using \(\pi\approx3.14\), we have \(C = 3.14\times142=445.88\) m.

Step4: Round to the nearest whole number

Rounding \(445.88\) to the nearest whole number gives \(446\) m.

Answer:

\(446\)
