the diameter of a circle is 86 m. find the circumference to the nearest whole number.
answer attempt 1 out of 2
c - m submit answer

Explanation:

Step1: Recall 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 given diameter into the formula

Given \(d = 86\) m, so \(C=\pi\times86\). Using \(\pi\approx3.14159\), we have \(C = 3.14159\times86\).

Step3: Round to the nearest whole number

Rounding \(270.17674\) to the nearest whole number. Since the decimal part \(0.17674<0.5\), we get \(C\approx270\).

Answer:

\(270\)
