If the area of a circle is 28.26 cm?, what is the radius of the circle?

1 answer

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

Area = π * radius^2

Given that the area is 28.26 cm², we can plug this into the formula and solve for the radius:

28.26 = π * radius^2
radius^2 = 28.26 / π
radius^2 = 9
radius = √9
radius = 3 cm

Therefore, the radius of the circle is 3 cm.
