Step-by-step explanation:
All sides of a square are equal.
For this case, the first thing we must do is define a variable.

Therefore, we have:
Answer:

Answer:
3.98 meters
Step-by-step explanation:
First we need to know the formula for finding the height of a cylinder

Now That we know our formula, we just need to put in our numbers and simplify



9x+12=5x+4
9x-5x=12-4
4x=8
x=8/4
x=2
Well we know that every 2 eggs requir 1 and 3/4 of flour so the easiest thing to do here (for me at least) is to round the fraction to the nearest whole number which in this case will be 1. Now that that's done we can say every 2 eggs calls for 2 cups of flour. Now all you need to do is multiply 2 by 9 to get 18 then put that in fraction form it'll be 17 and 3/4 cups of flour. I hope this helps!
