Question
If ratio of the radii of two spheres is 3:7 , find the ratio of their volumes ?
Hint:
Volume of the sphere is 
The correct answer is: 27:343
Explanation:
- The radii of two sphere are in ratio 3:7
- We have to find the ratio of their volume
Step 1 of 1:
Let the ratio be
Radius of 1st sphere and radius of 2nd sphere 7r
Volume of 1st sphere
Volume of 2nd sphere
Their ratio will be
= 27:343
