ANSWER
The discriminant is -3
EXPLANATION
The given quadratic equation is:
Comparing this equation to:
we have
a=1, b=3, and c=-6
The discriminant is calculated using the formula,
We substitute the values to get:
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
