All I'm worried about it is (a); for now. Okay, so let's start off like this: I know what the question is asking, sort of. I know it wants the ratio of the inside corner pieces of the square to the square itself. But what??? I obviously know that $A_{circle}=\pi r^2$ and $A_{square}=wh$ and also that the piece they are looking for is $A_{circle}-A_{square}$ but the ratio? I don't understand that. Can someone explain to me what they mean by that and stay posted for I may have questions about (b)-(e). Thanks.

    They want $\frac{A_{square}-A_{circle}}{A_{square}}$2012-08-10

    $\dfrac{wh-\pi r^2}{wh}$?2012-08-10

    I think that you're just looking for the definition of a ratio. it just measure proportionally how much larger or smaller is one quantity when compared to another. For example, Profit Margin is the amount of net income generated per dollar of revenue, so the formula would be $$\frac{\text{net income}}{\text{total revenue}}$$. Similarly, problem (a) is asking for the proportion of the area of the square that is cover by its corners.2014-08-20
