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 ,
![\longrightarrow \pink{ \boxed{Volume \: of \: Cylinder = \pi r {}^{2}h }} \longleftarrow](https://tex.z-dn.net/?f=%3C%2Fp%3E%3Cp%3E%20%5Clongrightarrow%20%5Cpink%7B%20%5Cboxed%7BVolume%20%5C%3A%20%20of%20%5C%3A%20%20Cylinder%20%3D%20%5Cpi%20r%20%7B%7D%5E%7B2%7Dh%20%20%7D%7D%20%5Clongleftarrow)
Our solution starts from here :
![\longmapsto \: \pi \: r {}^{2} h = 225\pi](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5C%3A%20%5Cpi%20%5C%3A%20r%20%7B%7D%5E%7B2%7D%20h%20%3D%20225%5Cpi)
<u>Step </u><u>1</u><u> </u><u>:</u> Cancelling π with π :
![\longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5C%3A%20%20%5Ccancel%7B%5Cpi%7D%20%5C%3A%20r%20%7B%7D%5E%7B2%7D%20h%20%3D%20225%20%5Ccancel%7B%5Cpi%7D)
<u>Step </u><u>2</u><u> </u><u>:</u> Substituting value of radius which is 5 cm in the formula :
![\longmapsto \: (5) {}^{2} \times h = 225](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5C%3A%20%285%29%20%7B%7D%5E%7B2%7D%20%20%5Ctimes%20h%20%3D%20225)
![\longmapsto \: 25h = 225](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5C%3A%2025h%20%3D%20225)
<u>Step </u><u>3 </u><u>:</u> Transposing 25 to right hand side :
![\longmapsto \: h = \frac{225}{25}](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5C%3A%20h%20%3D%20%20%5Cfrac%7B225%7D%7B25%7D%20)
<u>Step </u><u>4</u><u> </u><u>:</u> Cancelling 225 by 25 :
![\longmapsto \: \red{\boxed{h = 9 \: cm}}](https://tex.z-dn.net/?f=%20%5Clongmapsto%20%5C%3A%20%20%20%5Cred%7B%5Cboxed%7Bh%20%3D%209%20%5C%3A%20cm%7D%7D)
- <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>
