EXPERTS/ACE/GENIUSES PLZ HELP QUICK!!:) THANKS.
Rina8888 [55]
Hey there Hailey!

So, to start this all of, what formula are we even going to use.

The formula that we will be using in this question would be . . .

\left[\begin{array}{ccc}\boxed{V= \pi r^2 \frac{h}{2}} \end{array}\right]

So, now that we know what formula that we will use, we will now plug in those number's into the formula.

Justification:

We do, 9 = (height)*3=(radius) \ but \ using \ the \ formula \ also.


\left[\begin{array}{ccc}27*3.14= \boxed{84.78} \\ Your \ correct \ answer \ would \ be \ \boxed{\boxed{27}}\end{array}\right]

Hope this helps you!
