The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle. In this case, the area is given as 28.26 cm^2.
28.26 = πr^2
To find the radius, we can rearrange the formula:
r^2 = 28.26/π
r^2 = 9
r ≈ 3 cm
Therefore, the radius of the circle is approximately 3 cm.
If the area of a circle is 28.26 cm2, what is the radius of the circle?(1 point) cm
