Question

the diameter of a circle is 28 millimeters. what is the circles circumfer
round your answer to the nearest hundredth.
millimeters

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 value of \(d\)

Given \(d = 28\) mm, substitute into the formula: \(C=\pi\times28\).

Step3: Calculate the value

Using \(\pi\approx3.14159\), we have \(C = 3.14159\times28=87.96452\).

Step4: Round to the nearest hundredth

Rounding \(87.96452\) to the nearest hundredth (two - decimal places), we look at the third decimal digit. Since \(4<5\), we keep the second decimal digit as it is. So \(C\approx87.96\).

Answer:

\(87.96\)
