Answer:

18 inches

Step-by-step explanation:

a=\pi r^2

This is the formula for finding the area of a circle. We already know the area, so we'll move the terms in the equation to better fit our purposes.

r=\sqrt(\frac{a}{\pi} )

Now let's substitute.

r=\sqrt(\frac{324\pi}{\pi} )

We'll cancel out unnessicary terms:

r=\sqrt(324)

This gives us the following:

r = 18

In other words, the radius of the circle is 18 inches (NOT square) :D hope this helps :D
