Step 2: Write out the given values and substitute them into the formula
Therefore,
Hence, the area in terms of pi is
The last choice is the correct answer
For this case we have that if the line that passes through point z is perpendicular to line AB, it is fulfilled that:
We find the slope of AB:
We choose the points that go through AB:
(-2.4)
(0, -4)
So:
On the other hand, the point z is (0,2).
Then the cut point with the "y" axis is 2.
The equation of the line is:
We test the points:
(-4,1)
Is fulfilled
(1, -2)
It is not true
(2,0)
It is not true
(4,4)
It is not true
