I can't see a figure, but I assume the 4 circles are arranged in a square. Each circle has a diameter of 12 inches, so let's consider the 12" square forming one quarter of the figure.
Area of square is 144; area of circle in square is 36pi. Each corner outside the square thus has area 1/4 (144-36pi) = 36-9pi.
The center area, consisting of 4 of these areas, thus has area 144-36pi.
SUrely the shaded area can be figured from these data.
