Question

1. a wheel has a radius of 35 centimeters.

a. determine its circumference.

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 into the formula

Given \(r = 35\) cm, substitute into \(C = 2\pi r\). So \(C=2\times\pi\times35\).

Step3: Calculate the value

\(C = 70\pi\). Using \(\pi\approx3.14\), we get \(C\approx70\times3.14 = 219.8\) cm.

Answer:

The circumference of the wheel is approximately \(219.8\) cm.
