Okay, so I did my math homework, and I end up getting a radius of 8.9 and a height of 28. So I'm good with the math. I want to know wether to right the dimensions like this:
radius x height
or
height x radius.
Or does it really matter? (I'm pretty sure it does.)
My teacher is picky, so I need to get it right. Thanks!

It should be write, not right.

It was an optimization problem, so I needed to find the maximum dimensions a cylinder could have in order to have a volume of 84.
Thanks everyone for your answers.

Okay! I got it. Thanks everyone. :)

It's not the radius at all. Are you look for the surface area or the volume when you say dimensions? Volume is the area of the circle/base (that you find using the radius) times the height. Surface area would be the area of the circle/base times 2 plus the height times the circumference of the circle/base.
Folks -- radius * height is *not* the formula for either surface area, nor volume

Hmm; the way you put it, I don't think it would matter as long as you specify which was which. If you just write 8.9 X 28 and your teacher expects height X radius, then you're wrong. Not knowing which is the "standard" in your class, I would write something like "radius X height = 8.9 X 28", so that I'm hopefully covered even if the preferred order is wrong.

To define a cylinder you need only 2 numbers: radius and height
Radius can be determined by diameter as it is 1/2 diameter, so a cylinder can also be defined by diameter and height.
It is irrelevant which you put first (radius x height and height x radius are mathematically synonymous)
Best of luck!
