Question

find the circumference of this circle. use 3.14 for π. 5 cm circumference of a circle c = πd = 2πr c = ? cm round your answer to the nearest tenth.

Explanation:

Step1: Identify the formula

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

Step2: Substitute the values

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

Step3: Calculate

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

Answer:

\(31.4\)
