**msp**, Thursday, March 6, 2008 at 10:51am* area of a circle is r^2 times pi

r=9s so r^2 is 9s^2. Multiply this by 3.14 to get the area of the circle. You can't actually solve it with a number since there is a variable involved.

* Area of a square is length times width

* If s=1, the area of the circle is 9^2 x 3.14. Take this answer and subtract it from the area of your square.

Hope this helps. Good luck!
