The formula for the area of a circle is given by 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

Now we need to solve for the radius (r). First, divide both sides by π:

28.26 / π = r^2

Simplify the left side:

r^2 ≈ 9

Take the square root of both sides to solve for the radius:

r ≈ √9
r ≈ 3

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