By definition, the volume of a cylinder is given by:
Where,
r: cylinder radius
h: cylinder height
From here, we clear the height.
We have then:
Then, replacing values we have:
Answer:
The least possible height of the container is 9 inches.
I couldn’t remember how to solve this problem, so I just took a guess based off of similar problems. I believe it is wrong becau
se when you add up my two answers for EF and FG (to the right. 15 and 18) it obviously doesn’t equal 12 like EG is supposed to. Could someone tell me either what I might have done wrong, or if I just completely did everything wrong? I thought maybe if I solved for X and then plugged that in it would give me the answers, so that’s what I tried to do.

Answer:
Step-by-step explanation:
1). 10 =
10(7 + x) = 1 + 7x
70 + 10x = 7x + 1
10x - 7x = 1 - 70
3x = -69
x = -23
2). 0.2 =
0.2(12 + x) = 6 + 2x
2.4 + 0.2x = 6 + 2x
2.4 - 6 = 2x - 0.2x
1.8x = -3.6
x = -2
3). 0.8 =
0.8(x + 0.5) = x
0.8x + 0.4 = x
x - 0.8x = 0.4
0.2x = 0.4
x = 2
4). 3.5 =
3.5(0.5 - x) = 4 + 2x
1.75 - 3.5x = 4 + 2x
-3.5x - 2x = 4 - 1.75
-5.5x = 2.25
x = -
x = -
Answer:
15 units
Step-by-step explanation:
The picture of the question in the attached figure
we know that
Triangle XYZ is a right triangle, because segment ZY is tangent to circle X at point Y
so
Applying the Pythagorean Theorem
we have
substitute the given values
