OpenStudy (jokersmart):

\[A. 54\pi \]

OpenStudy (campbell_st):

simply square the radius... then multiply by the height... and write the answer as \[answer ~\pi ~units^3\]

OpenStudy (jokersmart):

\[B. 108\pi \]

OpenStudy (jokersmart):

\[C. 162\]

OpenStudy (jokersmart):

\[D. 324\pi\]

Those are the answer choices.

OpenStudy (campbell_st):

so the units of measurement are cubic feet...?

OpenStudy (jokersmart):

That or C... not too sure. I'll figure it out

OpenStudy (campbell_st):

the solution is \[radius^2 \times Height ~ \pi ~units^3\]

OpenStudy (jokersmart):

D?

OpenStudy (campbell_st):

r = 0.5 height = 0.75 \[V = 0.5^2\times 0.75 \pi ~feet^3\]
