Radius squared pi
WebAgain, the formula can be used to solve for the radius, if you know the area. Simply divide a by π to get r² and take the square root of the result. If you wish to know the diameter from the area, follow the procedure above but double the result you get for r. This is because the diameter is twice the length of the radius.
