Best ResponseYou've already chosen the best response.1this might be be more helpful \(1−\frac {πr^2}{(2r)^2} \)

Best ResponseYou've already chosen the best response.1Mhm ok well I think the problem you're having is understanding where the area comes from...so let me put it as simple as I can. So here is a square dw:1439326678199:dw the area is "inside" the square. So far so good?

Best ResponseYou've already chosen the best response.1dw:1439326963001:dw so since the length of all the sides are the same for the square we let the side = a, and to find the total area, we then take the length and multiply it by the width \[A_{\square} = lw = a \times a = a^2\]
