answer is
Step-by-step explanation:
a metallic sphere is melted and recasted into 216 balls it means its volume is same so
volume of 216 balls is equal to the volume of sphere
hence
volume of sphere is 4/3 pie r cube
r = 42cm
now
calculations are
4/3 × 22/7×42×42×42
4×22×2×42×42 = 216 × 22/7 × rcube
