Question 3 A spherical ball of radius 3 cm is melted and recast into three spherical balls.
The radii of the two balls are 1.5 cm and 2 cm respectively. Determine
the diameter of the third ball.

the diameter of the third ball is 2.5 cm

Step-by-step explanation:

The computation of the diameter of the third ball is as follows:

As we know that

The Volume of a sphere is

=

(3)^3 = (1.5)^3 + (2)^3 + (r)^3

r^3 = 15.625

r = 2.5 cm

hence, the diameter of the third ball is 2.5 cm

We simply applied the above formula so that the correct value could come

And, the same is to be considered

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

the 3rd option is right
