Question

e.mccormick · Answer

Because that is a square, the area has a direct relationship to the length of the sides.  Do you know how you could use that to find what you need for the area of a circle?

Not really, sorry.

e.mccormick · Answer

Well, think about this for a second.  What is the formula for the area of a circle?

anonymous · Answer

Sorry schools computer is freezeing and everything, Area is Pie * Rsquared right? new here so no clue how/if you can put the actuall symbols.

e.mccormick · Answer

Equation editor or LaTeX for $\pi r^2$

Now, the square touches both ens of the line that goes through the center of the circle.  So the side of the square is the diameter of the circle.  Does that give you a good enough clue on what you need to find out about the square so that you can bring it to the circle's area formula?
