Help please!!!

OpenStudy (tylermckinney16):

Questions here.

OpenStudy (aravindg):

Do u know formula for area of cone?

OpenStudy (tylermckinney16):

a little

OpenStudy (tylermckinney16):

yeah

OpenStudy (sagewilson):

\[V = \pi R^{2}\frac{ H }{ 3 }\]

OpenStudy (sagewilson):

R = 6 H = 9

OpenStudy (sagewilson):

\[V = \pi 6^{2}\frac{ 9 }{ 3 }\]

OpenStudy (sagewilson):

I can't believe you've been waiting for 2 hours.

OpenStudy (tylermckinney16):

Lol Yeah i half to get this work done.

OpenStudy (sagewilson):

WHAT! what! Omg- I thought you were asleep and left the tab open like I sometimes do. Anyways I'll help you out.

OpenStudy (tylermckinney16):

Thanks lol and no i stayed up yesterday pass five lol im a schoo aholic lol i always half to get work done lol. and thanks.

OpenStudy (sagewilson):

Well you're certainly more dedicated than most people. V=π(6^2)(9/3) V = π(36)(3) V = 3.14 * 36 * 3 V = 113.04 * 3 V = 339.12

OpenStudy (tylermckinney16):

^^^ Is that the answer or just the formula?

OpenStudy (sagewilson):

Both.

OpenStudy (tylermckinney16):

So i put that down for the answer XD?

OpenStudy (sagewilson):

Yup, put everything if you want to show your work though.

OpenStudy (tylermckinney16):

Thanks ill do that ima put two more questions will u help?

OpenStudy (sagewilson):

Sure.

OpenStudy (tylermckinney16):

OpenStudy (sagewilson):

\[V = \frac{LWH}{3}\] \[912^{3} = \frac{?x?x19}{3}\]

OpenStudy (tylermckinney16):

Ok

OpenStudy (sagewilson):

So you need to figure out what times what times 19 divided by 3 makes 912. Normally I would just plug in different numbers and hope for the best.

OpenStudy (sagewilson):

just think of 2 random numbers.

OpenStudy (tylermckinney16):

oh ok

OpenStudy (sagewilson):

Okay I got it. it's 12 for both L and W

OpenStudy (tylermckinney16):

ok and what next?:)

OpenStudy (sagewilson):

I'll need to figure out how to explain it in steps.

OpenStudy (tylermckinney16):

ok take ur time :)

OpenStudy (sagewilson):

Okay looks like I was wrong about the formula, it would be this: \[V = \frac{ b ^{2} H}{ 3 }\] Still the answer would be 12. I'm going to put it step by step for you. \[912 = \frac{ b ^{2} 19 }{ 3 }\] \[2Base = 3 * \frac{ 912 }{ 19 }\] \[2Base = 3 * 48\] \[2Base = 144\] \[2Base / 2 = 144 / 2\] \[Base = 12\]

OpenStudy (sagewilson):

Oh my gosh that took a lot of research. Just a question, what grade are you in?

OpenStudy (sagewilson):

@TylerMckinney16 don't be gone, you need this info.

OpenStudy (tylermckinney16):

Im here :) so 12 is the answer?

OpenStudy (sagewilson):

yes, but it said to show your work so there you go. Also what grade are you in?

OpenStudy (tylermckinney16):

im in 11th.

OpenStudy (sagewilson):

cool, so am I but I've never gotten anything like this. Must be because of different schools. Anyways next question.

OpenStudy (tylermckinney16):

ok hold on ill send it.

OpenStudy (sagewilson):

Okie doke.

OpenStudy (sagewilson):

hey do you think we can continue this tomorrow? if that's a possibility.

OpenStudy (tylermckinney16):

yeah sounds good cause ihalf to clean ill just tag u in a post if i put it on and u can check tomorrow.

OpenStudy (sagewilson):
