Question

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

Explanation:

Step1: Identify the radius

The radius \(r = 5\) cm.

Step2: Use the circumference formula

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

Step3: Substitute the values

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

Step4: Calculate

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

Answer:

\(31.4\)
