The area of a circle is modeled by the equation
A
=
π
r
2
. Rewrite the equation in terms of the circle’s radius
r
. In your final answer, include all of your calculations.
To rewrite the equation in terms of the circle's radius r, we simply solve for r:
A = πr^2
Divide both sides by π:
A/π = r^2
Take the square root of both sides:
√(A/π) = r
Therefore, the equation rewritten in terms of the circle's radius r is:
r = √(A/π)
