A) \[\sqrt{3}\,\,cm\]
B) 2 cm
C) 3 cm
D) 4 cm
Correct Answer: D
Solution :
Let radius of each sphere = r cm Then, \[12\times \frac{4}{3}\,\,\pi {{r}^{3}}=\pi \,\,{{\left( \frac{16}{2} \right)}^{2}}\times 2\] \[16{{r}^{3}}=64\times 2\] \[{{r}^{3}}=8\] \[r=2\,\,cm\] Hence, the diameter of each sphere = 4 cm
