Question

the radius of a circle is 47 millimeters. what is the circles circumference? round your answer to the nearest hundredth. millimeters

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 \(r = 47\) mm. Substitute into the formula: \(C=2\times\pi\times47\).

Step3: Calculate the value

\(C = 94\pi\). Using \(\pi\approx3.14159265\), then \(C\approx94\times3.14159265\).
\(94\times3.14159265=(90 + 4)\times3.14159265=90\times3.14159265+4\times3.14159265\)
\(90\times3.14159265 = 282.7433385\), \(4\times3.14159265=12.5663706\)
\(C\approx282.7433385+12.5663706=295.3097091\approx295.31\)

Answer:

\(295.31\)
