A "Norman" window is a rectangular window with a semicircle mounted along the top edge. If the window is to have a total area of 30 square meters, what is the minimum perimeter of the window? Round to two places. Hint: Let r be the radius of the semicircle and y be the height of the rectanglar portion. You will likely want to immediately replace π with 3.142. If r is the radius of the semicricle and y is the height of the rectangular portion and P is the total perimeter, write a formula for P in terms of r only. (It should start P = ...) We want to minimize P in the equation The minimum perimeter is: P = meters.
