Find the dimensions of the rectangle so that its area is a maximum. My Try: Let length of the side be x , Then the length of the other side is 2 r 2 − x 2, as shown in the image. Then the area function is A ( x) = 2 x r 2 − x 2
WebLet’s use some calculus to derive the answer.: We can model a semicircle as a stack of infinitesimally thin strips. If we sum the moment of all these strips, normalised over the area of the entire half-circle, we can find the centroid. The centroid is the location that we can model the shape as if the entire weight acts through this point. WebNow let’s apply this strategy to maximize the volume of an open-top box given a constraint on the amount of material to be used. Example 4.33 Maximizing the Volume of a Box An …
