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:
\(A = \pi r^2\)
In this problem, the area is less than 1 dm², hence:
\(A < 1\)
\(\pi r^2 < 1\)
\(r < \sqrt{\frac{1}{\pi}}\)
\(r < 0.56\)
The radius of the circle is less than 0.56 dm.
