Design the Sphere class $in$ python such that the following output is produced. Hints:

Volume of the sphere $=\frac{4}{3}****r^3,$ where $r=$ radius of the sphere and $=3\mathrm{.}1416.$

Merging spheres together conserves the total volume. The volume of the bigger sphere

can be calculated by adding the volume of the spheres being merged. $[$see pictures for

details$].$ Pay attention to how the object is updated.

When spheres of different colors are merged together then the merged sphere will have

'Mixed Color' instead of one particular color.

Your code should work for any number of Sphere objects passed to the merge$\_$sphere$()$ method.

The default value of the radius $r$ is $1.$
