Question

the circumference of a circle is 6.28 millimeters. what is the circles radius?
c = 6.28 mm
round your answer to the nearest hundredth.
millimeters

Explanation:

Step1: Write the formula for circumference

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

Step2: Solve for \(r\)

Given \(C = 6.28\) mm and \(\pi\approx3.14\), substitute into the formula:
\(6.28=2\times3.14\times r\)
First, calculate \(2\times3.14 = 6.28\). Then the equation becomes \(6.28 = 6.28r\).
Divide both sides by \(6.28\): \(r=\frac{6.28}{6.28}\)

Answer:

\(1.00\) millimeters
