Question

which of the following is closest to the circumference of a circle that has a radius of 4 units? 2 of 4 questions 12.57 units 6.28 units 60.26 units 25.13 units

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given radius into the formula

Given \(r = 4\) units, substitute into \(C = 2\pi r\). So \(C=2\times\pi\times4 = 8\pi\).

Step3: Calculate the value

Taking \(\pi\approx3.1416\), then \(C = 8\times3.1416=25.1328\) units.

Answer:

25.13 units
