In the following figure, what is the area of the shaded circle inside of the square?
the figer is shaded circle inside squar and it touchs the sides of the aquare
Since they don't give you the length of one side of the square assign it a variable:
Let x = length of one side of square
the radius of the circle must be x/2
Area of any circle is (pi)r^2
So, the area of the circle (based on x) is
