Question

a circle has a diameter of 12 centimeters. which measurement is closest to the circumference of the circle in centimeters?
37.68 cm
14.13 cm
18.84 cm
144 cm

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given \(d = 12\) cm and using \(\pi\approx3.14\), we have \(C\approx3.14\times12\).

Step3: Calculate the value

\(3.14\times12 = 37.68\) cm.

Answer:

37.68 cm
