How do You Find the Diameter of a Circle?

To find the diameter of the circle you will need to know either the radius, area or the circumference. If you know the circumference then divide it by Pi (3.142) to get the diameter. If you know the radius then just multiply it by 2. Finally if you know the area (which is the hardest to figure) then you multiply 4 by the area divide by pi and then figure the square root.
