This is an equation I got from Bert Pool's file.

    EQUATION 10: CAPACITANCE OF A TOROID
                                                    ___________________
                                                   /    2
         C =(1+ (0.2781 - d2/d1)) x  2.8  x      /  2 pi  (d1-d2)(d2/2)
                                               /   -------------------
                                            \/      4 pi


     C = capacitance in picofarads (+- 5% )
    d1 = outside diameter of toroid in inches
    d2 = diameter of cross section (cord) of toroid in inches

CAN ANYONE help me solve for D1 as in D1=........
I have been trying to do this without any results (I suck at math)

Thank You
