Answer: v = [tex]81\pi[/tex]

Step-by-step explanation:

Start the problem with what you know:

  • The formula for the volume of a cylinder is [tex]v = \pi r^2h[/tex]
  • r is the radius, r = 3
  • h is the height (in this case length), h = 9

Now plug in the numbers you have:

[tex]v = \pi r^2h \\[/tex]

[tex]v = \pi (3)^2(9)\\[/tex]  

[tex]v = \pi (9*9) \\[/tex]

[tex]v = 81\pi[/tex]
