Solving for the Radius of a Circle
The formula for the area of a circle is given by A = πr^2, where A is the area and r is the radius of the circle.
To solve for the radius r, we need to rearrange the formula:
A = πr^2
We want to isolate r, so we divide both sides by π:
A/π = r^2
Next, to solve for r, we need to take the square root of both sides:
r = √(A/π)
This matches with option C:
C. r = √(A/π)
