So, yes. But that is the non-rounded version.

The formula for the area of a circle is A = πr², where A is the area and r is the radius.
We are given that the area of the circle is 28.26 cm². Therefore:
28.26 = πr²
To solve for r, we need to isolate the variable by dividing both sides by π and then taking the square root:
r² = 28.26/π
r = √(28.26/π)
Using a calculator, we can evaluate this expression to get:
r ≈ 3 cm
Therefore, the radius of the circle is approximately 3 cm.
