The radii of two sphere are in the ratio 3 : 2. Their volumes will be in the ratio :
A. 9 : 4
B. 8 : 27
C. 27 : 8
D. 3 : 2
Answer: Option C
Solution (By Examveda Team)
Let the radii of the two spheres be 3r and 2r respectivelyThen, required ratio :
$$\eqalign{ & = \frac{{\frac{4}{3}\pi {{\left( {3r} \right)}^3}}}{{\frac{4}{3}\pi {{\left( {2r} \right)}^3}}} \cr & = \frac{{27}}{8} \cr & = 27:8 \cr} $$
