Integrale con valore assoluto

L'integrale di |z| sulla sfera x^2 + y^2 + z^2 <= 4, a me torna 8pi greco, mentre invece nelle soluzioni torna 4 pi greco (scritto meccanici 2011_2)
L'ho riguardato molte volte, è la soluzione che è errata oppure ho sbagliato un passaggio?

L'ultima riga mi torna così

pie[-cos(2phi)] * [rho^4 / 4] con 0<=phi<=pie/2 e 0<=rho<=2
