If you have the volume, that's a pretty good giveaway that you ought to use
the formula for the volume of a cylinder, since it involves all the other things ...
the things you're given, and the things you need to find. If you know the formula
for the volume of a cylinder, you can whip out the answer in a second. If you don't
know the formula, then you are toast.
Volume of a cylinder = (pi) (radius)² (length or height)
Divide each side of the equation by (pi) x (height) and you have
(Radius)² = Volume / (pi x height)
You HAVE volume and height, so you can use this equation to calculate
the radius. Once you have that, if you need the diameter, it's just double
the length of the radius.
That's how.
Answer:
45 dollars
Step-by-step explanation:
20 plus 10 is 30. That means she gets a total of 30 dollars off. Subtract 30 from the original price of 75, and you get 45 dollars.
The answer I got would be 2(x+18)
So, Noah would most likely have - wait hold up what's the main question?is it how much Noah has? if it is I will be able to solve it. Or is it how much water will fill it or something?
Remember, -(-x)=x because the negatives cancel out
so
when p=-6 and q=7
p+(-q)-3
-6+(-7)-3
-6-7-3
-13-3
-16
