Vocaloid (vocaloid):

have you found the products yet?

OpenStudy (weasel123):

CHOCOLATE!!!!

OpenStudy (tylermckinney16):

No i have not.

Vocaloid (vocaloid):

well go ahead

OpenStudy (tylermckinney16):

I cant find any good ones.

Vocaloid (vocaloid):

try 'pyramid container'

OpenStudy (tylermckinney16):

ok

Vocaloid (vocaloid):

pick 3 that you like

Vocaloid (vocaloid):

actually cylinders might be easier since the volume is usually listed

OpenStudy (tylermckinney16):

ok ill look for some then

Vocaloid (vocaloid):

do you know how to calculate the volume?

OpenStudy (tylermckinney16):

OpenStudy (tylermckinney16):

heres two more.

Vocaloid (vocaloid):

good but make sure you save the link

Vocaloid (vocaloid):

the info we need is at the bottom of each page

OpenStudy (tylermckinney16):

ok

Vocaloid (vocaloid):

well, do you know how to calculate the volume?

OpenStudy (tylermckinney16):

No.

Vocaloid (vocaloid):

volume = pi*height*(1/2 * diameter)^2

Vocaloid (vocaloid):

so for the green one, what's the volume?

OpenStudy (tylermckinney16):

Volume = π×8.42×10 = 2216.707776373 centimeter3??

Vocaloid (vocaloid):

not quite.

Vocaloid (vocaloid):

look at the formula I gave you carefully.

OpenStudy (tylermckinney16):

Ok

OpenStudy (tylermckinney16):

The diameter is 8.4 on the green one.

Vocaloid (vocaloid):

yeah, but what's the radius?

Vocaloid (vocaloid):

if the diameter is 8.4, what is the radius?

OpenStudy (tylermckinney16):

10?

Vocaloid (vocaloid):

hint: radius = (1/2)*diameter

OpenStudy (tylermckinney16):

so its 1/2?

Vocaloid (vocaloid):

think carefully.

Vocaloid (vocaloid):

radius = (1/2) * diameter

Vocaloid (vocaloid):

* means multiply

OpenStudy (tylermckinney16):

4.2??

Vocaloid (vocaloid):

good. now use the formula volume = pi*height*r*r what do you get?

Vocaloid (vocaloid):

(r is the radius)

OpenStudy (tylermckinney16):

553.896??

Vocaloid (vocaloid):

good. now compare that to the capacity listed on the item

Vocaloid (vocaloid):

if it's not listed, try another item

Vocaloid (vocaloid):

then repeat the same process I told you for the other items good luck!

OpenStudy (tylermckinney16):

ok :)

Vocaloid (vocaloid):

gtg but tag someone if you need help

Directrix (directrix):

@TylerMckinney16 The original question you posted states that you are to find 3 Amazon products that are pyramids or cones and then to crank out the volume of each. What I see in this thread are cylinders. To my thinking, you should consider closing this thread and starting over. @Vocaloid posted >>actually cylinders might be easier since the volume is usually listed That is correct but you are instructed to find pyramids and/or cones.

OpenStudy (tylermckinney16):

ok hold on ill start it over and tag u in it.
