Using the equation of the area of a circle, it is found that the radius of the circle is less than 0.56 dm.
What is the area of a circle?
The area of a circle of radius r is given by:
[tex]A = \pi r^2[/tex]
In this problem, the area is less than 1 dm², hence:
[tex]A < 1[/tex]
[tex]\pi r^2 < 1[/tex]
[tex]r < \sqrt{\frac{1}{\pi}}[/tex]
[tex]r < 0.56[/tex]
The radius of the circle is less than 0.56 dm.
