Answer:

3 cm

Step-by-step explanation:

The formula for the area of a circle is:

[tex]A = \pi r^2[/tex]

Where "r" represents the radius of the circle. We can substitute the given value for Area into the equation to solve for the radius.

Solve for Radius

[tex]A=\pi r^2\\9\pi = \pi r^2[/tex]

Divide both sides by π

[tex]9=r^2[/tex]

Take the square root of both sides

[tex]\sqrt9=\sqrt {r^2}\\r=3[/tex]

The radius of the circle is 3 cm.
