>>15261068Area of whole square: 4x4=16 square units
Area of whole circle: pi x 2^2= 12.6 square units
Area outside of circle: 16-12.6=3.4 square units
Area in each corner: 3.4 / 4 = 0.85 square units
This is a right angle triangle of walls 2 and 4, so the smaller angle is 30 degrees and larger is 60 degrees. You just have to divide the area outside of the circle by 3 because 30degreesx3 is 90. so the answer is 0.283333... sq units.
