NEED HELP PLEASE!!!!

OpenStudy (anonymous):

A cone has a radius of 5 inches and a height of 18 inches. What is the exact volume of the cone? A. 150π in3 B. 300π in3 C. 450π in3 D. 540π in3

OpenStudy (aggie12341):

C

OpenStudy (anonymous):

in ^3

OpenStudy (anonymous):

aggie

OpenStudy (anonymous):

Do you know the equation to use?

OpenStudy (anonymous):

idk

OpenStudy (pinklion23):

hey @aggie12341 how do you know the answer to this but you dont know the answer to 9+10

OpenStudy (anonymous):

@iGreen @ParthKohli @BlossomCake

OpenStudy (anonymous):

pinklion please no disrespect

OpenStudy (anonymous):

no insults plz @pinklion23

OpenStudy (anonymous):

answermyquestions will help

OpenStudy (anonymous):

The formula for the volume of a cone is \(\dfrac{1}{3}\) x radius x height

OpenStudy (pinklion23):

sorry :'( i did not want to be mean

OpenStudy (anonymous):

V=πr2h 3\[Volume= \pi r^2\frac{ H }{ 3}\]

So many people. ._.

OpenStudy (anonymous):

Guys

OpenStudy (anonymous):

Calm down, guys!

OpenStudy (anonymous):

can u break that down @YesThisIsDog

OpenStudy (anonymous):

O.o

OpenStudy (igreen):

\(V = \dfrac{1}{3} \pi r^2 h\) Plug in the values but don't simplify pi

OpenStudy (anonymous):

yep @horsegirl325 \[\pi*5^2*\frac{ 18 }{ 3 }\]

OpenStudy (igreen):

\(V = \dfrac{1}{3}(5^2)(18)\)

OpenStudy (igreen):

That will give you your answer in terms of pi.

OpenStudy (anonymous):

i got 471

OpenStudy (igreen):

No..that's wrong.

OpenStudy (igreen):

@YesThisIsDog That is also incorrect.

OpenStudy (anonymous):

No, Horse, that is correct.

OpenStudy (igreen):

Multiply 1/3 * 5 * 5 * 18

OpenStudy (anonymous):

150?

OpenStudy (igreen):

@YesThisIsDog It doesn't want you to simplify pi

OpenStudy (igreen):

Correct

OpenStudy (igreen):

So our answer is \(150 \pi\)

OpenStudy (anonymous):

NO, 471.24 is the volume...

OpenStudy (anonymous):

thx

OpenStudy (igreen):

Yes, and that is not a choice.

OpenStudy (anonymous):

y'all never let me finish explaining.... Jesus.

OpenStudy (igreen):

@YesThisIsDog \(150\pi \approx 471.24\)

OpenStudy (anonymous):

GO on girl!

OpenStudy (anonymous):

I was getting to that-.-

OpenStudy (igreen):

Yes, but it wants the exact volume.

OpenStudy (anonymous):

YES @iGreen I KNOW. I WAS JUST ABOUT TO FINISH THE DAMN THING.

OpenStudy (anonymous):

FIGHT! FIGHT! FIGHT!

OpenStudy (igreen):

xD

OpenStudy (igreen):

No need for language @YesThisIsDog It's just that, you told her to multiply pi..

OpenStudy (igreen):

Okay, you have your answer..

OpenStudy (anonymous):

so its 150?
