<u>Step-by-step explanation:</u>
Here we have , building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π, pi meters. We need to find What is the area A of the cross section of the column .Let's find out:
We know that , Circumference of circle =
⇒
⇒
⇒
⇒
⇒
We know that area of circle =
⇒
⇒
⇒
Therefore , the area A of the cross section of the column is .
