Question

the radius of a circle is 9 m. find its circumference in terms of $\pi$. answer attempt 1 out of 2 $c =$ m submit answe $\pi$

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given radius

Given \(r = 9\) m. Substitute into the formula: \(C=2\pi\times9\).

Step3: Calculate the result

\(C = 18\pi\)

Answer:

\(18\pi\)
