niran has 72 centimeter of molding to make a frame for a print. how should he cut the molding to give the largestpossible area for the print using the inside edge of the moldin as the perimeter

  • advanced 6th grade - ,

    The question does not state the shape of the print. The largest area is made by NOT cutting the moulding and bending the moulding into a circle.

    Radius will be 72/2xpi =11.46 cm

    Area = pi r^2= 3.142 x 11.46cm^2= 412 cm^2

    By comparison if the moulding is cut into 4 equal pieces the area is
    18cm^2 = 324 cm^2
