To find the radius of the circle, you can use the formula for the area of a circle: A = πr².
Given that the area of the circle is 28.26 cm², the formula becomes:
28.26 = πr²
To solve for r, you can rearrange the formula:
r² = 28.26 / π
r² = 9
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
