i need help

OpenStudy (anonymous):

hey Nnesha! its me again so you are trying to find the volume of this solid figure, right?

OpenStudy (anonymous):

do you know how to find the volume of a cylinder?

OpenStudy (anonymous):

very good! did we talk about that yesterday? i think we did

OpenStudy (anonymous):

anyways

OpenStudy (anonymous):

we have to plug in the variables

OpenStudy (anonymous):

do you want me to check if your work is correct?

Nnesha (nnesha):

sure

OpenStudy (anonymous):

okay then

OpenStudy (anonymous):

what are you using for pi?

OpenStudy (anonymous):

3.14?

OpenStudy (anonymous):

i didnt get 226.

Nnesha (nnesha):

no i just use pi in buttion

OpenStudy (anonymous):

lets look back at what you did. the equation is \[\pi \times height \times radius squared \]

OpenStudy (anonymous):

did you dived the width by two?

OpenStudy (anonymous):

cuz we are supposed to square the radius, not the diameter

OpenStudy (anonymous):

oh okay i see what you did here.

OpenStudy (anonymous):

you have to divide 6 by two

OpenStudy (anonymous):

then that gets you three

OpenStudy (anonymous):

that is what you square

Nnesha (nnesha):

oh ok 57

OpenStudy (anonymous):

not quite

OpenStudy (anonymous):

cuz you have to get both of them to be inches

OpenStudy (anonymous):

one is feet and one is inches

OpenStudy (anonymous):

so get the two feet to equal ____ inches

OpenStudy (anonymous):

what does two feet equal in inches?

OpenStudy (anonymous):

no, not yet. we have to convert the 2 feet to inches. remember?

OpenStudy (anonymous):

so what does 2 feet in inches equal?

Nnesha (nnesha):

ohhh ok

OpenStudy (anonymous):

yaa! you got it! so two feet is equal to 24 inches. i know you know that ;)

Nnesha (nnesha):

yeah :)

OpenStudy (anonymous):

so what do we do now?

OpenStudy (anonymous):

we multiply pi by 9 and by 24

Nnesha (nnesha):

and then 679 dan dana :) :P

OpenStudy (anonymous):

yayyyyyyyyy!!!!!! nice job!!!

Nnesha (nnesha):

OpenStudy (anonymous):
