Question

# A Hollow sphere of internal and external diameters of 6 cm and 10 cm respectively is melted into a cone of 8 cm base diameter . Find the height of the cone ?

Hint:

### Volume of the cone is

Volume of hollow sphere

## The correct answer is: 24.499cm

### Explanation:

- We have given a Hollow sphere of internal and external diameters of 6 cm and 10 cm respectively is melted into a cone of 8 cm base diameter.
- We have to find the height of the cone.

Step 1 of 1:

We have given a hollow sphere with internal and external diameter 6cm, 8cm, repectivley.

The inner and outer radius if the sphere will be 3cm, 4cm

So,

The volume of the hollow sphere will be

Now the sphere is melted into cone with diameter

So, The volume of the material of sphere = volume of the cone

So,

V = 410.50

h = 24.499cm

Now the sphere is melted into cone with diameter

So, The volume of the material of sphere = volume of the cone

So,
