A) 2 : 3
B) 3 : 2
C) 1 : 2
D) 2 : 1
Correct Answer: A
Solution :
Let the volumes be \[{{V}_{1}}\] and \[{{V}_{2}}\]. \[\therefore \] \[{{V}_{1}}:{{V}_{2}}=8:27\] \[\Rightarrow \] \[\frac{2}{3}\pi r_{1}^{3}:\frac{2}{3}\pi r_{2}^{3}=8:27\] \[\Rightarrow \] \[r_{1}^{3}:r_{2}^{3}=8:27\] \[\therefore \] \[{{r}_{1}}:{{r}_{2}}=2:3\]
