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 plug this into the formula:
28.26 = πr^2
To solve for r, we can rearrange the formula:
r^2 = 28.26 / π
r^2 = 9
r = √9
r = 3
Therefore, the radius of the circle is 3 cm.
