Base = 2 x height (b = 2h)
Area = 1/2 x base x height = 1/2 x 2h x h = h x h = h^2
In order to solve the formula

in terms of d, you simply have to divide both sides by pi:

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

So, the total height is
