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?
What I tried:
Do you use the 40y feet and add it with the number of sides there are (4) for the perimeter? And then subtract it from the area given? What do you do with pi leave as is?

-------------
The area of the square is (40y)^2 = 1600y^2
Minus the circle --> 1600y^2 - 100piy^2 = 100y^2*(16 - pi) sq ft
