To find the radius of a circle given the area, you can use the formula for the area of a circle which is A = πr^2. Given that the area is 28.26 cm^2, we can plug this into the formula:
28.26 = πr^2
Now, solve for r by dividing both sides by π and then taking the square root:
r^2 = 28.26/π
r = √(28.26/π)
r ≈ √(9)
r ≈ 3 cm
Therefore, the radius of the circle is approximately 3 cm.
28.26 = πr^2
Now, solve for r by dividing both sides by π and then taking the square root:
r^2 = 28.26/π
r = √(28.26/π)
r ≈ √(9)
r ≈ 3 cm
Therefore, the radius of the circle is approximately 3 cm.
