Question

the diameter of a circle is 16 kilometers. what is the circles circumference? round your answer to the nearest hundredth. kilometers

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

Given \(d = 16\) kilometers. Substitute into the formula: \(C=\pi\times16\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), then \(C = 16\times3.14159=50.26544\).

Step4: Round to the nearest hundredth

Rounding \(50.26544\) to the nearest hundredth (two decimal places). The third - decimal digit is \(5\), so we round up the second - decimal digit. \(50.26544\approx50.27\).

Answer:

\(50.27\) kilometers
