If the area of a circle is 28.26 cm2, what is the radius of the circle? Plz help bot

Answer 1

To find the radius of the circle, we need to use the formula for the area of a circle:

A = πr^2

Given that the area is 28.26 cm^2, we can substitute this into the formula:

28.26 = πr^2

To solve for the radius (r), we need to isolate r by dividing both sides of the equation by π:

r^2 = 28.26 / π
r^2 = 9
r = √9
r = 3 cm

Therefore, the radius of the circle is 3 cm.
