Answer: option C
Step-by-step explanation:
You need to use the formula for calculate the area of a circle:

Where the radius of the circle is "r".
You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:

Where "d" is the diameter of the circle.
Then, the radius is:

Finally, substitute the radius into the formula. Then, the area of the circle is:

Answer:
the matrix described in the question is a linearly independent matrix, and linearly dependent matrix has a unique solution. <em>see further explanation below</em>
Step-by-step explanation:
For any matrix to have a pivot column in all its column, it means that the matrix must be linearly dependent
Thus, as the columns are linearly independent , the system of equation have a unique solutions
