Question

the radius of a circle is 18 ft. find its circumference in terms of $pi$. answer attempt 1 out of 2 $c=\text{______} \text{ ft}$

Explanation:

Step1: Recall the circumference formula

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

Step2: Substitute the given radius

Given $r = 18$ ft, substitute into the formula: $C=2\pi\times18$.

Step3: Simplify the expression

$C = 36\pi$ ft.

Answer:

$36\pi$
