Expert Answer:
Recasting won't change the volume.
Let D1,D2,D3,Do be the diameters of the three recast balls and the initial spherical ball respectivley.
Volume of ball 1 + Volume of ball 2 + Volume of ball 3 = Volume of spherical ball
πD13/6 + πD23/6 + πD33/6 = πD03/6
D13 + D23 + D33 = D03
D33 = D03 - ( D13 + D23)
= 33 - ((3/2)3+23)
=125/8
D3 = 5/2
The diameter of the third ball is 5/2 cm.
