What is the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters?

To find the area of the circle, use the formula ( A = \pi r^2 ). With a diameter of 3 meters, the radius is 1.5 meters, resulting in an area of approximately ( 7.07 , \text{m}^2 ). The area of the square is ( 3 \times 3 = 9 , \text{m}^2 ). Therefore, the difference in area is approximately ( 9 - 7.07 = 1.93 , \text{m}^2 ).
