Question

the circumference of a circle is 43.96 millimeters. what is the circles radius? c = 43.96 mm 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 \(C\) is the circumference and \(r\) is the radius.

Step2: Solve for \(r\)

We know \(C = 43.96\) mm. Rearranging the formula \(C = 2\pi r\) for \(r\), we get \(r=\frac{C}{2\pi}\). Substitute \(C = 43.96\) and \(\pi\approx3.14\) into the formula: \(r=\frac{43.96}{2\times3.14}\).
First, calculate \(2\times3.14 = 6.28\). Then \(r=\frac{43.96}{6.28}\).
\(43.96\div6.28 = 7.00\)

Answer:

\(7.00\)
