Question

the diameter of a circle is 12 m. find its circumference in terms of π.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the value of diameter

Given \(d = 12\) m. Substitute \(d\) into the formula: \(C=\pi\times12\).

Answer:

\(12\pi\) m
