Revisiting the floating ball: we solved the equation

on the interval from d = 0 to d = 4. If you graph the function 62.4π d2(2 − d/3) and the constant function 436 on the span from d = −2 to d = 7, you will see that this equation has two other solutions. Find these solutions. Is there a physical interpretation of these solutions that makes sense?
