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 is 28.26 cm^2, we can plug this into the formula:

28.26 = πr^2

To find the radius, we need to isolate r:

r^2 = 28.26 / π
r^2 = 9
r = √9
r = 3 cm

Therefore, the radius of the circle is 3 cm.
