Question

a circle has a circumference of 22π centimeters. what is the diameter, in centimeters, of the circle?
11
16
22
44

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given value into the formula

Given \(C = 22\pi\), substitute into \(C=\pi d\): \(22\pi=\pi d\).

Step3: Solve for \(d\)

Divide both sides of the equation \(22\pi=\pi d\) by \(\pi\). We get \(d = 22\).

Answer:

22
