How can a value in a point dataset attribute table be used to define the total area of a buffer around a point?

I want to create buffers around points, where the area of the buffer is equal to an area value specified in the attribute table of the point dataset. Generally in ArcMap a buffer distance is specified in the buffer tool, which is essentially the radius of the buffer circle. I don't have this distance but have the area which I want the total buffer area to be. I have tried creating a new field for a buffer distance, and used field calculator to work out the radius of a circle with the area values, however this equation includes the pi sign which I am unsure how to include in the field calculator.
