Question

# The radius of the base of a circular cone Is halved. Keeping the height same , What is the ratio of the volume of the reduced cone to that of the original cone ?

Hint:

### Volume of the cone is

## The correct answer is: 1/8

### Explanation:

- We have given the radius of the base of a circular cone Is halved. Keeping the height same
- We have to find ratio of the volume of the reduced cone to that of the original cone

Step 1 of 1:

Let the radius of the cone initially be r

The radius of new reduced cone will be

The volume of original cone initially is

And the volume of reduced cone is

So, the ratio will be

So, the ratio will be
