To find a area of a sheded region u need to subtract two area
area of a circle and area of a hexagon
Area of circle=pi*r^2
where r=2 inch
A=12.56 inches^2
Area of hexagon would be areas of 6 eqaul forming triangles=6*1/2B*H
A=3*6*4=72 inch
now u just need to subtract those areas
72-12.56=59.22 inches^2
