OpenStudy (anonymous):

i dont get it

OpenStudy (goldphenoix):

Is your final answer, 150.72 ?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

its wrong

OpenStudy (goldphenoix):

To find the volume of the cylinder, you want to use the formula: \[\large \large V = hr^2pi\]

OpenStudy (goldphenoix):

So the radius is 6. What would 6^2 give you?

OpenStudy (anonymous):

12

OpenStudy (goldphenoix):

Nope. 6 *2 = 12. Another way of writing 6^2 is: 6 * 6. What does 6 *6 give us?

OpenStudy (anonymous):

36

OpenStudy (goldphenoix):

Great! Now multiply it by 3.14 to find the area of the circle. So what does 36 * 3.14 give us?

OpenStudy (anonymous):

113.04

OpenStudy (goldphenoix):

Now multiply it by the height, which is 8. So 113.04 * 8 = ?

OpenStudy (anonymous):

904.32

OpenStudy (goldphenoix):

Good job! So the voume of the cylinder is 904.32 mm^3. I hope this help! :)
