Building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18 \pi18π18, pi m

Ksivusya [100]

the area A of the cross section of the column is $(81\pi )m^2$ .

<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 = $2\pi r$

⇒ $Circumference = 2\pi r$

⇒ $18\pi= 2\pi r$

⇒ $\frac{18\pi}{2\pi }= \frac{2\pi r}{2\pi }$

⇒ $\frac{18\pi}{2\pi }=r$

⇒ $r=9$

We know that area of circle = $\pi r^2$

⇒ $Area= \pi r^2$

⇒ $Area= \pi 9^2$

⇒ $Area= 81\pi$

Therefore , the area A of the cross section of the column is $(81\pi )m^2$ .
