Answers
GPT 3.5
To find the radius of the circle, we use the formula for the area of a circle:
Area = π * radius²
Given that the area of the circle is 28.26 cm², we can set up the equation as:
28.26 = π * radius²
To solve for the radius, we need to divide both sides of the equation by π:
radius² = 28.26 / π
radius² = 9
Taking the square root of both sides gives us the radius:
radius = √9
radius = 3 cm
Therefore, the radius of the circle is 3 cm.
Area = π * radius²
