Write the Area of a circle formula and solve for r

Answer 1

The area of a circle formula is A = πr^2, where r is the radius of the circle.

To solve for r, we can rearrange the formula as follows:
A = πr^2
r^2 = A/π
r = √(A/π)

Therefore, the value of r is equal to the square root of the area divided by π.
