A rectangle is inscribed in a circle of radius 6 (see the gure)' Let P=(x,y) bathe point in quadrant I that is a vertex of the rectangle and is on the cirde. Answer the following questions (a) Express the area A of the rectangle as a function of x. A(x)= 4x435 -x2 (h) Express the perimeter p of the rectangle as a function of x. V p[x]= 4x+4J36-x2 (c) Graph A=A(x). For what value of K is A largest? ' x 5:: 4.24 (Use the MAXIMUM function. Round to two decimal places.) (d) Graph p= pm. For what value of x is p largest? x 5:: (Use the MAXIMUM function. Round to two decimal places.)
