The area of the cross section of the column is 
Explanation:
Given that a building engineer analyzes a concrete column with a circular cross section.
Also, given that the circumference of the column is
meters.
We need to determine the area of the cross section of the column.
The area of the cross section of the column can be determined using the formula,

First, we shall determine the value of the radius r.
Since, given that circumference is
meters.
We have,

Thus, the radius is 
Now, substituting the value
in the formula
, we get,


Thus, the area of the cross section of the column is 
Answer:
<em>See Reasoning Below</em>
Step-by-step explanation:
To prove that AB = BL, or in other words AB ≅ BL, let us consider the triangles CED and BEL. If we were to prove they were congruent, then by CPCTC ( corresponding parts of congruent triangle are congruent ) DC ≅ BL. As AB ≅ DC by " Properties of Parallelogram " it would be that through transitivity, AB ≅ BL / AB = BL;

Now for " part 2 " we can consider that AB = DC, from part 1. If AB = BL, then AL = 2 ( AB ) by the Partition Postulate. AB = DC, so we can also say that AL = 2 ( DC ) - Proved

Answer:
Step-by-step explanation:
6 = 2(1+2)
Use distributive property (Multiply 2 and 1. Then multiply 2 and 2)
6 = 2+4
Now add
6=6
This means the statement is true
Good luck I’m actually looking for answers just like this
x=34 is the correct answer!
