Move all terms not containing z to the right side of the equation.
Z=5
the area A of the cross section of the column is .
<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 .
B. when something is at rest it has balanced forces. And unbalanced when it's moving.<span />
T (-1, 3) is vertically 2 units away from the line y = 1.
When finding the ordered pair for the new point, M, it must also be 2 units from the line y = 1, but on the opposite of the line. The x-value will not change only the y-value.
Counting two units BELOW the line we get M(-1, -1)
