this is the only question in this section.
question
the radius of a circle is 7 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 \(C = 2\pi r\), where \(r\) is the radius.

Step2: Substitute the given radius

Given \(r = 7\) m. Substitute \(r = 7\) into the formula: \(C=2\pi\times7\).

Step3: Calculate the result

\(2\pi\times7 = 14\pi\) m.

Answer:

$14\pi$ m
