If the area of a circle is 28.26 cm^2, what is the radius of the circle?

Answer 1

To find the radius of a circle when given the area, we can use the formula:
Area of a circle = π * (radius)^2

Given that the area of the circle is 28.26 cm^2, we can set up the equation:
28.26 = π * (radius)^2

Solving for the radius:
radius^2 = 28.26 / π
radius^2 ≈ 9
radius ≈ √9
radius ≈ 3 cm

Therefore, the radius of the circle is approximately 3 cm.
