Best ResponseYou've already chosen the best response.1We just need to divide the area of the circle by the area of a square, so what is the area of a square and circle?

Best ResponseYou've already chosen the best response.1Area of a square is side * side right? So we can say \[A_{\square} = a^2\] and area of a circle is \[A_{circle} = \pi r^2\]

Best ResponseYou've already chosen the best response.1Geny, I provided you the formulas, you learn this in elementary. You just remember them for now, now since the radius is half the size of the side of a square we will let 2r be the side of the square, so we have a = 2r putting it all together we have \[A_{\square} = (2r)^2~~~~A_{circle}=\pi r ^2\]

Best ResponseYou've already chosen the best response.1So we have \[\frac{ \pi r ^2 }{ (2r)^2 }\]

Best ResponseYou've already chosen the best response.1@geny55 have you found the area that is in the square but not in the circle?

Best ResponseYou've already chosen the best response.1hint: to find that area you will need to find the difference between the square's area and the circle's area

Best ResponseYou've already chosen the best response.1notice the square's side length is given by (4+4) and the circle's radius is given by 4 it should be pretty easy to find the areas of both the square and circle now and you want to know the difference of these areas over the squares area
