[AI-generated answer — Bot GPT 3.5]

The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.

Given that the area of the circle is 28.26 cm^2, we can set up the equation:

28.26 = πr^2

To find the radius, we need to isolate r by dividing both sides by π and then taking the square root:

r^2 = 28.26 / π
r = √(28.26 / π)

Calculating this out, we get:

r ≈ √(9)
r ≈ 3 cm

Therefore, the radius of the circle is approximately 3 cm.
