First find the square root of 900 to get one side of the square, which is 30 inches.
Formula for area of a circle: pi times the radius(squared)
The radius is 15 because one side of the square equals the diameter of the circle. 15 squared is 225.
3.14x225=706.5 inches squared
I hope this helps, because I did not have a diagram of the problem, but this should be the answer if the circle is inscribed in the square.
