Answer:
So the radius is increasing at
.
This is approximately 0.00497 cm/min that the radius is increasing.
Step-by-step explanation:

The volume and radius are both things that are changing with respect to time.
So their derivatives will definitely not be 0.
Let's differentiate:

I had to use constant multiple rule and chain rule.
We are given
and
.
We want to find
.
Let's plug in first:



Multiply both sides by 3:


Divide both sides by
:


So the radius is increasing at
.
This is approximately 0.00497 cm/min that the radius is increasing.
Answer:
x=9
Step-by-step explanation:
2x=x+9
Subtract x from both sides;
2x-x=x+9-x
Simplify;
x=9
