Answer:

32pi - 64

Step-by-step explanation:

The two UNshaded areas are equal to each other. Each one is the

Area (square) - 1/4 Area(circle)

64 - 1/4 (64pi)

64 - 16pi

There are 2 of these unshaded pieces in this question.

Area (square) - 2 (64 - 16pi)

64 - 128 + 32pi

= -64 + 32pi

Area = 32pi - 64
