Answer:

2 * (Area/pi)^(1/2) = diameter

Step-by-step explanation:

The equation for the area of a circle is A = pi * r^2

We can divide both sides by pi to get:

A/pi = r^2

Then take the square root of both sides to get:

(A/pi)^(1/2) = r

Then, since D = 2 * r, we can multiply both sides of the above equation by 2 to get:

2 * (A/pi)^(1/2) = 2 * r = D
