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 
Angle c is angle t on the dashed figure
Answer:
x + y < 20
5x + 10y ≥ 100
Step-by-step explanation:
The ski club wants at least $100
Student pays $5
Chaperone pays $10
Maximum number of seats = 20
Assumption:
Assumed number of students = x
Assumed number of chaperone = y
Equation:
Maximum number of seats = 20
⇒ x + y < 20
The club wants $100
⇒ 5x + 10y ≥ 100
Answer:
The ratios are not equivalent
Step-by-step explanation:
First, in order to find the ratios, we have to change the month to the amount of days.
There are 30 days in April, so we will use this for the ratio.
The ratio for the 3 day weekend is 5:3
The ratio for the month of April is 60:30, which can be simplified to 2:1
So, the ratios are not equivalent, because 5:3 is not equal to 2:1
