Length of AC = $$6sqrt{2}$$ cm Let side of square = $$x$$ cm = Diameter of circle In $$ riangle$$ ABC, => $$(AB)^2 + (BC)^2 = (AC)^2$$ => $$(x)^2 + (x)^2 = (6sqrt{2})^2$$ => $$2x^2 = 72$$ => $$x^2 = frac{72}{2} = 36$$ => $$x = sqrt{36} = 6$$ cm Thus radius of circle = $$frac{6}{2} = 3$$ cm $$ herefore$$ Area of circle = $$pi r^2$$ = $$pi imes (3)^2 = 9pi$$ $$cm^2$$ => Ans - (A)
