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:
A
Step-by-step explanation:
The definition of a parrelelogram is "a four-sided plane rectilinear figure with opposite sides parallel". Since you already know that EH and Fg are equal because of the black ticks on them. Now you only need to find out wheter or not EF≅HG to meet the criteria of a parrelologram.
Answer:
The second one:
L∪J={i,j,k,l,m,n,o}
Step-by-step explanation:
The union is the elements listed in either set.
So since l,m,n, and o are elements of set L, they will also be elements of whatever it is "unioned" with.
Since i,j,k,l and m are elements of set J, they will also be elements of whatever it is "unioned" with.
When you write the union, just be sure to include each element that occurs in either set once.
So the union of L and J is {i,j,k,l,m,n,o}.
The answer is the second one.
The intersection would actually be that upside down U thing, the ∩ symbol. The intersection of two sets is a list of elements that both sets include. So here the intersection would just consist of the elements l amd m.
Answer: 36
Step-by-step explanation: We can actually mental math this question, since perfect squares are squares obviously, 6 squared is <u>36</u>. Hope this helps, 15402256!
