1. The problem statement, all variables and given/known data A decorative window has the form of a rectangle surmounted by a semicircle whose diameter is equal to the top of the rectangle. If the TOTAL perimeter of the window 16+pi, then what is the maximum area? A. 25.653 B. 32.148 C. 15.923 D. 38.047 E. 30.018 Correct answer is A: 25.653, but explain step by step please. 2. The attempt at a solution I completely started off on the wrong foot here. What I did was made the radius = x/2 where x is the total width/diameter of the rectangle/circle. Then I made the equations: P=2∏(x/2)+2x+2y=16+pi A=∏(x/2)^2+xy=z I seem to not be getting the answer after I plug everything in, so I know im starting off wrong. Please explain by a step-step process. Thanks in advance.
