please anyone answer me tomorrow is my examination​

Answer 1

Answer:

12 cm.

Step-by-step explanation:

When the given process is done, the volume of the metal remains constant.

So, volume of the 3 spheres = volume of the final sphere.

Let the radius of the final sphere be ''r''.

=>  $\frac{4}{3}\pi (6)^{3}+ \frac{4}{3}\pi(8)^{3}+ \frac{4}{3}\pi(10)^{3}= \frac{4}{3} \pi(r)^{3}$

=>  $r^{3} = 216+512+1000= 172 8=12^{3}$

=>  r = 12 cm.
