Question

I don’t know which one to select

Answer 1

`\sf{\bold{\green{\underline{\underline{Given}}}}}`

⠀⠀⠀⠀

• V = π r² h

______________________

`\sf{\bold{\green{\underline{\underline{To\:Find}}}}}`

⠀⠀⠀⠀

• Correct option = ??

______________________

`\sf{\bold{\green{\underline{\underline{Solution}}}}}`

⠀⠀⠀⠀

V = π r² h

⠀⠀⠀⠀

• Using equations formulae

⠀⠀⠀⠀

`\sf (V)/(\pi) = r² h`

⠀⠀⠀⠀

`\sf (V)/(\pi* r^2) = h`

⠀⠀⠀⠀

• checking correct option

⠀⠀⠀⠀

Option 1 :

⠀⠀⠀⠀

`\sf \bigg( h = (V)/(\pi r^2) \bigg) \\eq ( h = V - \pi r^2)`

⠀⠀⠀⠀

This option is not correct

⠀⠀⠀⠀

Option 2 :

⠀⠀⠀⠀

`\sf \bigg( h = (V)/(\pi r^2) \bigg)` =
`\sf \bigg( h = (V)/(\pi * r^2) \bigg)`

⠀⠀⠀⠀

This option is correct

⠀⠀⠀⠀

Option 3 :

⠀⠀⠀⠀

`\sf \bigg( h = (V)/(\pi * r^2) \bigg) \\eq ( h = V\pi r² )`

⠀⠀⠀⠀

This option is not correct

⠀⠀⠀⠀

Option 4 :

⠀⠀⠀⠀

`\sf \bigg( h = (V)/(\pi * r^2) \bigg) \\eq ( h = V - \pi - r^2)`

⠀⠀⠀⠀

This option is not correct

• Correct answer = option B

Answer 2

B

Explanation:

Divide by pir^2 to get h all by itself and you'll have V/pir^2 = h
