The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
Given that the area is 28.26 cm^2, we can plug this into the formula:
28.26 = πr^2
To find the radius, we need to isolate r:
r^2 = 28.26 / π
r^2 = 9
r = √9
r = 3 cm
Therefore, the radius of the circle is 3 cm.
If the area of a circle is 28.26 cm2
, what is the radius of the circle?
