Answer:

3 cm

Step-by-step explanation:

The formula for the area of a circle is:

A = \pi r^2

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

<h3>Solve for Radius</h3>

A=\pi r^2\\9\pi = \pi r^2

Divide both sides by π

9=r^2

Take the square root of both sides

\sqrt9=\sqrt {r^2}\\r=3

The radius of the circle is 3 cm.
