Question

the diameter of a circle is 2 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 \(d = 2\) kilometers. Substitute into the formula: \(C=\pi\times2\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), then \(C = 2\times3.14159=6.28318\).

Step4: Round to the nearest hundredth

Rounding \(6.28318\) to the nearest hundredth (two - decimal places). The third decimal digit is \(3\), so we keep the second decimal digit as it is.

Answer:

\(6.28\) kilometers
