Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
We have r = 3in and H = 9in. Substitue:

Answer:
Option B. 4<=x<=6 is the solution set.
If f(x)=6x+2,
f(x+3)=6(x+3)+2
f(x+3)=6x+18+2
f(x+3)=6x+20
The answer is C I’m pretty sure
Step-by-step explanation:
13x+2=54
subtract 2 from both sides.
13x=54
divide both sides by 13
x=4.
