If the area of a circle is 28.26 cm", what is the radius of the circle?
To find the radius of the circle, you can use the formula for the area of a circle:
A = πr^2
Given that the area of the circle is 28.26 cm^2, you can substitute this value into the formula:
28.26 = πr^2
Next, solve for the radius (r):
r^2 = 28.26 / π
r ≈ √(28.26 / 3.14159)
r ≈ √9
r ≈ 3
Therefore, the radius of the circle is approximately 3 cm.
