Question

the radius of a circle is 2 miles. what is the circles circumference? round your answer to the nearest hundredth. miles

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \( C = 2\pi r\), where \(r\) is the radius.

Step2: Substitute the given radius

Given \(r = 2\) miles, substitute into the formula: \(C=2\pi\times2\).

Step3: Calculate the value

\(C = 4\pi\). Using \(\pi\approx3.14159\), \(C\approx4\times3.14159 = 12.56636\).

Step4: Round to the nearest hundredth

Rounding \(12.56636\) to the nearest hundredth gives \(12.57\).

Answer:

\(12.57\)
