Oh, I should have caught onto that.

I'm fine without points, I just was curious why my answer was downvoted. Thank you for explaining.

Can you give us all the information you have (like the actual problem)?

All you need to do is convert 2/3 into an integer. You can do this by dividing 2 by 3 either on paper or with the site calculator. When you write down the answer you will need to know that when you have a repeating decimal, there is a line over the part that repeats.

I'm not certain, but I think you have to subtract 5 - (-5) = 5 + 5 = 10 for the function. Then you replace all of the x's in $${{\mathtt{x}}}^{{\mathtt{4}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{x}}}^{{\mathtt{2}}}$$ + 5x with 10's. Doing that, we have $${{\mathtt{10}}}^{{\mathtt{4}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{10}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}}{\mathtt{\,\times\,}}\left({\mathtt{10}}\right)$$. $${{\mathtt{10}}}^{{\mathtt{4}}} = {\mathtt{10\,000}}$$, $${{\mathtt{10}}}^{{\mathtt{2}}} = {\mathtt{100}}$$, 5(10) = 50 . Then we have 10000+100+50 which can be easily added together to get the answer.

Yes, but you need to know the height.

Why did someone downvote my answer? It is accurate.

They were asking for radius not volume, so I was confused. If they only have the volume, then the problem can't be answered.

What information do you already have about the cylinder?

First convert them to common denominators: 3/4 x 5/5 = 15/20

Then you add the numerators of 15/20 + 7/20 and keep the denominators.
