This being the second dumb mistake I've made tonight, perhaps a sign to go to sleep, yes? ha.

anonymous · Answer

its ok. haha. it happens. just gotta big test tmrw evening and i wanna make sure i am on the right track

anonymous · Answer

You might try plugging in for: r = 6, h = 2...and your answer may magically reveal 24pi !

anonymous · Answer

so am i over thinking this than?

anonymous · Answer

6x6=36 x2=72/3

anonymous · Answer

=24?

anonymous · Answer

Remember to plug in 6, not 12 , for the radius into the formula that savinand gave earlier and you should have 24pi in^3.

anonymous · Answer

ok because the diameter of the base is already given..you use the radius of the base to find the volume. okay. thank u. i was given a practice sheet either from a copy made from someone elses answers but i wanted to practice myself and i had a feeling 288 was wrong
