Answer 1

@johnweldon1993 or anyone

Answer 2

So the equation would be

\[\large V = \frac{\pi r^2 h}{3}\]

So plugging everything in we have

\[\large V = \frac{3.14\times 9^2 \times 12}{3}\]

What does that come out to equal?

Answer 3

35532.2

Answer 4

Not quite...so we have

\[\large \frac{3.14 \times 81 \times 12}{3}\]
