Question 1025622
A square stained glass window has a green glass circle in the center. The length of the window is 40y feet and the area of the circle is 100piy^2 feet. What is the area of the glass surrounding the circle?  
-------------
The area of the square is (40y)^2 = 1600y^2
Minus the circle --> 1600y^2 - 100piy^2 = 100y^2*(16 - pi) sq ft
