Radius-14
Height-16

k_lynn · Answer

The volume formula of a cylinder is $$V=\Pi r ^{2}h$$R being the radius and h being the height.  So all you have to do is plug the numbers in for the variables and solve the equation.

k_lynn · Answer

Pi is also equivalent to 3.14.

k_lynn · Answer

So, once the numbers are correctly substituted, it should look like this $$3.14\times14^{2}\times16$$OR....$$3.14\times14\times14\times16$$

k_lynn · Answer

So what do you get when you do that math @doresmith

anonymous · Answer

I got 9847.04 but its not one of the answer choices.

k_lynn · Answer

I got the same thing.  What are the answer choices?

anonymous · Answer

Is it B? cause what i did is the answer choices it also has the pi sign which probably have to multiple that with 3.14 which is the same answer as the one that we got.

anonymous · Answer

3136*3.14=9847.04

k_lynn · Answer

If it has the pi sign in the options, then all you do is not multiply pi in the equation.  So...
$$14^{2}\times16$$

k_lynn · Answer

Then once you get that answer, you put the pi sign back in $\pi$

anonymous · Answer

so which would be the answer choice?

k_lynn · Answer

All you have to do now, is finish that math: $$14\times14\times16$$ and then put $\pi$ in front of it.  Then you have your answer.

anonymous · Answer

So the correct answer is B?
