Explanation:
Answer:

Explanation:
Knowing that the volume of a sphere is V=(4/3)πr³ and 
We must find
when r=14cm
V=(4/3)πr³ ⇒

and r=14cm then

Note: as you can see the relationship of change of r with respect to t is negative because it is a decrease, and also its volume ratio
Answer: decantation and screening
