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 of the circle is 28.26 cm^2, we can set up the equation:
28.26 = πr^2
To solve for the radius, we will first divide by π:
r^2 = 28.26 / π
r^2 ≈ 9
Taking the square root of both sides, we get:
r ≈ √9
r ≈ 3
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?(1 point)
