Question

# Metallic spheres of radii 6 cm , 8 cm and 10 cm respectively are melted to form a single solid sphere . Find the radius of the resulting solid sphere ?

Hint:

### Volume of sphere is

## The correct answer is: r = 12cm

### Explanation:

- We have given Metallic spheres of radii 6 cm , 8 cm and 10 cm respectively are melted to form a single solid sphere
- We have to find radius of the resulting solid sphere.

Step 1 of 1:

We have given metallic sphere with radius 6cm, 8cm, 10cm

Volume of each sphere will be

And

And

Now, volume of big sphere will be equal to

So,

r = 12

Therefore, The radius of big sphere is r = 12cm.

And

And

Now, volume of big sphere will be equal to

So,

Therefore, The radius of big sphere is r = 12cm.
