"Less than" means subtraction
The order they appear in tells me to subtract 9 from N.
n - 9
Answer:

Step-by-step explanation:
I am going to assume your question meant the equation
So
can be found by substituting all the x terms in the equation with -1

And simplifying for our answer



The problem is asking for the height of the fluid using the following information:
Volume of fluid
=
V
=
36
π
cm
3
Radius of new cylinder
=
r
=
3
cm
To start the solution, solve for the height
h
in the formula for the volume of a cylinder:
V
