1. Find the perimeter of the square then the circumference of the circle then subtract the circle from the square. Area of square=length of side squared=9.8^2=96.04. Area of circle=(pi*radius)^2=((22/7)*(9.8/2))^2
2. Area of circle=pi*r squared 38.5=((22/7)*r)^2 Solve for r Square root of 38.5/(22/7))=r calculate area using above formula
