This is because when we plug in the value given in the picture.
Formula [tex]V=\pi r^{2} h[/tex]
The way we write this is by using our "r" which is 6. We plug in the 6 for "r" so the equation will look something like this: [tex]V=\pi (6)^{2} (h)[/tex]
Then we will plug in our height "h", which is 8. So the equation will look something like this: [tex]V=\pi (6)^{2} (8)[/tex]
So that's it. Very simple. Just remeber to keep the formula in mind and you will get the hang of it.
