Hello :Largest iin Area .... Thank you

4. It is fairly easy to show that the triangle with largest area inscribed in a circle is an equilateral triangle. Now, what do you mean by "create"? If the circle has radius R, then the inscribed equilateral triangle has side length [itex]\frac{2\sqrt{3}}{3}R[/tex] and area $\frac{1}{2}R^2$.
