Best Answer

That depends on what you know.

If you know the radius of the circle, double it to get the diameter.

If you know the circumference of the circle, divide it by π to get the diameter.

If you know the area of the circle, find its square root and divide the result by π to get the radius then multiply by 2 to get the diameter.
