What is the exact volume of the Cylinder? A. 1728mm3 B. 1728π mm3 C. 864mm3 D. 864πmm3

OpenStudy (studybird123):

The height is 24 mm and diameter 12

OpenStudy (anonymous):

I was going to ask for those

OpenStudy (anonymous):

do you know the radius?

OpenStudy (studybird123):

oh :)

OpenStudy (studybird123):

Online it says to find the radius divide the diameter by 2 so I guess its 6

OpenStudy (anonymous):

ok so it would be 3.14(6^2)(24)

OpenStudy (wolf1728):

Cylinder Volume = π • r² • height

OpenStudy (studybird123):

Well I kinda did that and keep getting 2712.96

OpenStudy (anonymous):

that is not one of your answers

OpenStudy (studybird123):

yeah I'm not sure what I'm doing wrong

OpenStudy (anonymous):

what unit of measurement is this?

OpenStudy (studybird123):

millimeters

OpenStudy (anonymous):

the answer you want is D because pi*864=2712.96 :)

OpenStudy (studybird123):

oh wow! I didn't notice that thank you so much! :)

OpenStudy (wolf1728):

24*36=864

OpenStudy (studybird123):
