Cut a circular sheet of iron with a radius of 2 decimeters into the largest square. What is the area of this square in square decimeters The process is to draw a square in a circle, not a circle in a square

The diagonal length of the largest square is the diameter length of the circle, so from the radius we can get that the length of the square is 2 * root 2. The area is 2 * 2 * 2 = 8dm2
