What do you think the answer is?

Use this formula \( V = \pi r^2 \frac{h}{3} \)

OpenStudy (anonymous):

452.39?

OpenStudy (anonymous):

452.16

OpenStudy (anonymous):

its 452.39, @chris0114792 your right.

OpenStudy (anonymous):

Wolfram says different. It stats 452.16 http://www.wolframalpha.com/input/?i=3.14+*+12%5E2+*+%283%2F3%29

Thanks man

OpenStudy (anonymous):

alyssa_nicole, you are incorrect.

OpenStudy (anonymous):

@alyssa_nicole the reason why you are getting 452.39 is because it is using a higher degree of accuracy when it comes to pi. The question stats to use 3.14 for pi. Google is using 3.14159265359, which makes it more accurate. This is also true when using a calculator. If you use 3.14, like the question ask, you will get 452.16
