A Norman window has the shape of a semicircle atop a rectangle so that the diameter of the semicircle is equal to the width of the rectangle. What is the area of the largest possible Norman window with a perimeter of 35 feet?I [l I have enough pure silver to coat 2 square meters of surface area. I plan to coat a sphere and a cube. Allowing for the possibility.r of all the silver going onto one of the solids, what dimensions should they be if the total volume of the silvered solids is to be a maximum? The radius of the sphere is l l metersr and the length of the sides of the cube is [1 meters. Again; allowing for the possibility of all the silver going onto one of the solids; what dimensions shouid the}; be if the total volume of the silvered solids is to be a minimum? The radius of the sphere is E' m, and the length of the sides of the cube is ll m
