Question

a circle has a diameter of 8 mm. what is its circumference? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Write the formula for circumference

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

Step2: Substitute the values

Given \(d = 8\) mm and \(\pi=3.14\), substitute into the formula: \(C=3.14\times8\).

Step3: Calculate the result

\(3.14\times8 = 25.12\).

Answer:

\(25.12\) mm
