For this case we have that by definition, the area of a circle is given by:
Where:
r: It is the radius of the circle.
So, we have that the area of the shaded region is given by:
We divide between 4 on both sides of the equation:
We apply root to both sides:
We choose the positive value of the root:
Finally, the value of "x" is 9
