What your doing is your going to answer how many points or sides the shape has like a squar has 4 corners
Bottom left. Because of th eminus sign, the v curve is "upside-down" and because of the +1, its function value peak is at 1
Area shaded = Area big circle- Area of small circle;
200 pi= pi•(2x)^2 -pi•6^2;
200pi= pi•4x^2 -pi•36;
200pi=pi•4(x^2 -9) divide both sides by 4pi;
50=x^2 -9; So x=sqrt(59)~7.68cm
