If the area of a circle is 28.26cm squared, what is the radius of the circle?
To find the radius of the circle, we can use the formula for the area of a circle:
A = πr^2
Given that the area is 28.26cm squared, we can plug this value into the formula:
28.26 = πr^2
To solve for the radius, we need to isolate r:
r^2 = 28.26 / π
r^2 = 9
r = √9
r = 3
Therefore, the radius of the circle is 3cm.
