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 1^{st} sphere and radius of 2^{nd} sphere 7r

Volume of 1^{st} sphere

Volume of 2^{nd} sphere

Their ratio will be

= 27:343
