As in the previous question, in this case also does the right hand side refers to the +ve root?

If so, then we can square the sides and the equation gives the area enclosed by a circle with center 0,0 and radius q^(3/2)

if the right hand side is negative, the above does not hold.

(1/8)*pi*q^3 = W
or w = (8w/pi)^(1/3)
