1. The problem statement, all variables and given/known data A Norman window has the shape of a rectangle with a semicircular top. Assume that the semicircular portion of the peripmeter is three times as costly to build per metre as the straight edges. For a given area, what ratio of heigh to radius would minimize the cost. 2. Relevant equations A diagram. r is radius, h is height. 3. The attempt at a solution [tex]P = (\pi r)+ 2r+ h + h[/tex] I'm not sure if this is right. It is asking for area so I should use [tex] S.A = (\pi r^2)/2 + 2rh[/tex]? I'm just having trouble setting up the equation.
