well; $V_{cone}=(1/3)(base.area)(height)$

base area is a circle so pi 5^2 = 25pi height has to be calculated for a rt tri with leg5 and leg13

why are people stealing my question???

simply plug in the given values into the equation: $V=1/3(\pi)(r^2)((h)$

thankyou amistre

sqrt(196+25) = sqrt(221) if i did it right

13^2 = 169 ...tho right lol

here is the muliple choice for that question

OpenStudy (bbb911):

no lmao ur just jealous so go shave urself

OpenStudy (amistre64):

169 +25 ---- 194 sqrt(194) = height then

A. 136.14 ft cube B. 314.16 ft cube C. 340.34 ft cube D. 408.141 ft cube

OpenStudy (amistre64):

$V_{cone}=\frac{25pi.\sqrt{194}}{3}$ if I did it right ...

so im guessing nobody knows the answer to the question

OpenStudy (amistre64):

there was a question?

OpenStudy (bbb911):

the question that stupid lmao put was originally mine not his or hers. and i put the multiple choice to prove it was mine

OpenStudy (amistre64):

ohhh.... someone pilfered your q ... got it.

OpenStudy (amistre64):

so; base area = 25pi; height = sqrt(13^2+5^2) Vcone = [25pi * sqrt(194)]/3 = abt 364.64...

OpenStudy (bbb911):

sooooo close its either C or D ... C is 340.34 ft cube and D. is 408.41 ft cube

OpenStudy (amistre64):

check to make sure all the info is right; you got a slant of 13 and a rad of 5?

OpenStudy (amistre64):

i see my mistake then

OpenStudy (amistre64):

$h^2 + 5^2 = 13^2$ $h=\sqrt{(169-25)}$ \[\h = \sqrt{144}=12]

6 years ago
OpenStudy (amistre64):

.... h = 12 25pi*12 ------ = 25pi *4 = 100pi, abt 314.16 3

yes and that is correct thank you sooo much
