What is the volume of a cylinder whose radius is 2 1/6x and the height is 1 1/2 inches? Find the volume in terms of x

Question

anonymous · Answer

volume of cylinder=$$\pi r ^{2}h$$
Put the values in terms of r and h, and get the answer.

anonymous · Answer

i got that part but i don't understand how to get from the radius being squared to the answer which has to be cubed since its volume

anonymous · Answer

Sec, I will do it.
$$\pi (21x/6)^{2} (11/2)$$\
It is not necessary for the answer to be x^3 if the parameters aren't that way.

anonymous · Answer

I thought that every answer that had to do with finding the volume always had to be cubed.

anonymous · Answer

Not really, not always I mean. You can have x squared and still have the right answer.  Just substitute the values.

anonymous · Answer

so would it be V=22.05x^2 inches^3 ??

anonymous · Answer

Yes.

anonymous · Answer

Assuming you did the calculations correctly.
