Question

a circle has a diameter of 12 units. what is the circumference, in units, of the circle? a 6π b 12π c 36π d 144π

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference \(C\) of a circle is \(C = \pi d\), where \(d\) is the diameter.

Step2: Substitute the given diameter into the formula

Given \(d = 12\) units. Substitute \(d = 12\) into \(C=\pi d\), we get \(C=\pi\times12 = 12\pi\).

Answer:

B. \(12\pi\)
