A) 32 cm
B) 18 cm
C) 24 cm
D) 21 cm
Correct Answer: D
Solution :
Suppose, r be the radius. \[\frac{4}{3}\pi {{r}^{3}}=49\times 33\times 24\] \[{{r}^{3}}=\frac{3\times {{7}^{2}}\times 3\times 11\times {{2}^{3}}\times 3\times 7}{{{2}^{2}}\times 2\times 11}={{3}^{3}}\times {{7}^{3}}\] \[\therefore \] \[r=3\times 7=21\,\,\text{cm}\]
