OpenStudy (logan13):

i think B

OpenStudy (anonymous):

A cylinder's volume is given by \[\pi*r^2* h\]

OpenStudy (logan13):

so B

OpenStudy (anonymous):

Did you plug into equation?

OpenStudy (logan13):

Yea

OpenStudy (anonymous):

Show me.

Just plug in values

geerky42 (geerky42):

here, we have \(r = 6\) and \(h = 9\)

geerky42 (geerky42):

plug into \(\pi ~r^2~h\)

OpenStudy (logan13):

how do i plug it in

geerky42 (geerky42):

\(\pi~\cdot~r^2~\cdot~h\) We have \(r = \color{red}{6}\) and \(h = \color{blue}{9}\) So volume is \(\pi~\cdot ~\color{red}{6}^2 ~\cdot~ \color{blue}{9}\)

geerky42 (geerky42):

is that clear? @logan13

OpenStudy (logan13):

so 9 x6

geerky42 (geerky42):

9 x 6 x 6

geerky42 (geerky42):

\(6^2\) means \(6\times6\)
