Question

the radius of a circle is 13 yards. what is the circles circumference? round your answer to the nearest hundredth. yards

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 \(r = 13\) yards. Substitute into the formula: \(C=2\times\pi\times13\).

Step3: Calculate the value

\(C = 26\pi\). Using \(\pi\approx3.1415926\), then \(C\approx26\times3.1415926 = 81.6814076\).

Step4: Round to the nearest hundredth

Rounding \(81.6814076\) to the nearest hundredth (two decimal places) gives \(81.68\).

Answer:

\(81.68\)
