Question

find the circumference.
5 cm
c =? cm
c = πd = 2πr
use π = 3.14

Explanation:

Step1: Identify 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 values

Given \(r=5\) cm and \(\pi = 3.14\). Substitute into the formula: \(C=2\times3.14\times5\).

Step3: Calculate the result

First, \(2\times5 = 10\), then \(10\times3.14=31.4\).

Answer:

\(31.4\)
