Question

the radius of a circle is 27 inches. what is the circles circumference? round your answer to the nearest hundredth. inches

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 \(r = 27\) inches. Substitute into the formula: \(C=2\times\pi\times27\).

Step3: Calculate the value

\(C = 54\pi\). Using \(\pi\approx3.1415926\), then \(C\approx54\times3.1415926 = 169.6460004\).

Step4: Round to the nearest hundredth

Rounding \(169.6460004\) to the nearest hundredth (two - decimal places) gives \(169.65\).

Answer:

\(169.65\)
