Question 336567
(1 pt) A Norman window has the shape of a rectangle surmounted by a semicircle. If the perimeter of the window is 37 feet, express the area A  of the window as a function of the width x  (across the base) of the window. 

let p=perimeter, x=width in feet, h=height A=area in feet^2

p=x+2*h+Pi*x=37 => h=(37-x-Pi*x)/2

A(x)=h*x+Pi*x^2=(37-x-Pi*x)*x+Pi*x^2=37x-x*x
