Answer:
- Height = <u>9</u><u> </u>cm which means <u>Option </u><u>C </u>is the answer
Step-by-step explanation:
In the question we are given ,
- Volume of cylinder = <u>2</u><u>2</u><u>5</u><u>π</u><u> </u><u>cm³</u>
- Radius of cylinder = <u>5 cm</u>
And , we have to find the <u>height</u><u> of</u><u> </u><u>cylinder</u><u> </u>.
We know that ,

Our solution starts from here :

<u>Step </u><u>1</u><u> </u><u>:</u> Cancelling π with π :

<u>Step </u><u>2</u><u> </u><u>:</u> Substituting value of radius which is 5 cm in the formula :


<u>Step </u><u>3 </u><u>:</u> Transposing 25 to right hand side :

<u>Step </u><u>4</u><u> </u><u>:</u> Cancelling 225 by 25 :

- <u>Henceforth</u><u> </u><u>,</u><u> </u><u>height</u><u> </u><u>of </u><u>cylinder</u><u> is</u><u> </u><u>9</u><u> </u><u>cm</u>

160 is 100% of 160, 480 is 4 times that. So 400%
3x - x + 8 + 5x - 2 = 10
combine like terms on the left, then add or subtract as asked
(3x - x + 5x) + (8 - 2) = 10
7x + 6 = 10
subtract 6 from both sides
7x = 4
divide both sides by 7
x = 4/7
Hope this helps! :)
Answer: x = 60
Step-by-step explanation:
the equation is a^2 + b^2 = c^2.
If you draw out the problem, you plug in the information into the formula, so it would be...
x^2 + 80^2 = 100^2.
80^2 = 6,400 and 100^2 = 10,000.
x^2 + 6,400 = 10,000.
You subtract 6,400 from itself and 10,000 and then you get...
x^2 = 3,600.
You square both of those and your final answer will be x = 60.
