The circle inside the large square below has an area of 71.4 cm 2 . Calculate the area of the large square. Note that the circle passes right through a number of grid intersection points. The square is not to scale, so the area is not 9x9. Use the formula for the area of a circle to solve for the radius. Then, notice that the radius takes up 2.5 units on the graph, so scale it until you have the entire length of one side of the square [Start by dividing the radius by 2.5 to get actual length of one unit (one little square), then multiple by the total number of little squares]. You will have one side and then you can solve for the area of the square. I solved and got 294.5 cm^2 but that is not the correct answer.
