OpenStudy (brucebaner):

\[v=1/3*3.14*30^2*17\]

OpenStudy (anonymous):

NOOOOO radius, they give u diameter

OpenStudy (anonymous):

\[15^{2}\]

OpenStudy (brucebaner):

i just remember

OpenStudy (anonymous):

and not 17, thats the slant, you need the height

OpenStudy (anonymous):

\[15^{2}+x ^{2}=17\]

OpenStudy (anonymous):

17^2***

OpenStudy (anonymous):

17^2=289 15^2=225 so x^2=64

OpenStudy (brucebaner):

so can you put the process

OpenStudy (anonymous):

yeah okay the height it 8 btw

OpenStudy (anonymous):

so \[v=\frac{ 1 }{ 3 }\pi15^2\]

OpenStudy (brucebaner):

got it D

OpenStudy (anonymous):

\[v=13π15^28\]

OpenStudy (brucebaner):

its D?

OpenStudy (anonymous):

sorry it keeps messing it up, lemme check

OpenStudy (anonymous):

yeah its D

OpenStudy (brucebaner):
