Hello, I have the volume of a cylinder: 250m ^ 3 with a radius of 1m. How can I find the height?

Thank you!

Hello! Sorry to bother you again, but I still don't understand this problem.

I have to do the comparison method with these two equations:

1 → 3x - y = 18

2 ⇾ -2y = -6x - 120

And when I isolated y, it gave me:

1 → y = 3x + 60

2 → y = 3x - 18

But it doesn't work !!! I came to an unrealistic answer. Can you help me isolate my equations, because I think I made a mistake please. It would help me enormously! Thanks in advance!

My teacher tells me that to work on fractions, it is useful to master LCM. How can I find it? I have heard of multiples and trees.

FastTamarind948

In my assignment, I am asked to find the LCM and the GCD of the following numbers: 10 and 15.

I know that LCM means least common multiple and GCD means greatest common divisor but I do not know their concrete definition.

Thank you very much for helping me, that will clarify everything

Hi, I'm not too good with taxes and discounts and everything. I am a little lost in this exercise:
