@KamiBug

c

OpenStudy (anonymous):

lol jk wrong awnser

OpenStudy (kamibug):

\[V = \pi * r^2 * \frac{ h }{ 3 }\]

OpenStudy (tylermckinney16):

B?

jhonyy9 (jhonyy9):

not B.

OpenStudy (kamibug):

6 is divided by 3, not 2. :)

OpenStudy (tylermckinney16):

6/3=2 XD?

OpenStudy (kamibug):

Right... so... ? :P

OpenStudy (tylermckinney16):

Which two is it theres one like 2^3 and another one.

OpenStudy (anonymous):

plz dont give awnsers because thates in code of conduct

OpenStudy (jdoe0001):

\(\textit{volume of a cone}=\cfrac{\pi r^2h}{3}\qquad \begin{cases} r=radius=\frac{diameter}{2}\\ h=height \end{cases}\)

OpenStudy (jdoe0001):

hint: diameter of the cone is 2in

OpenStudy (tylermckinney16):

I know but theres two answers with 2 in it lol C and D

OpenStudy (jdoe0001):

well, you're meant to get the volume, nevermind the letters the choices are there as guide only, not authority so, get the volume, whatever that is, and the choices MUST match your solution, not the other way around

OpenStudy (jdoe0001):

if the choices are good, then they will match you if they don't, then they're not good

OpenStudy (tylermckinney16):

I got the same thing as choice C. Does that look bout right?

OpenStudy (jdoe0001):

yeap

OpenStudy (jdoe0001):

\(\bf v=\cfrac{\pi r^2h}{3}\implies\cfrac{\pi \left( \frac{2}{2} \right)^2\cdot 6}{3}\implies \cfrac{\pi \cdot 1\cdot 6}{3}\implies \cfrac{\cancel{6}\pi }{\cancel{3}}\implies 2\pi \)

OpenStudy (jdoe0001):

wait a sec.. dohh man, I got to shoot with a bbgun =(

OpenStudy (jdoe0001):

hmmm nope... actually, is fine.. dohh anyhow, yes, you're correct, and C matches
