Question

I don’t know which one to select

Answer 1

Answer:

B

Step-by-step explanation:

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

Answer 2

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

⠀⠀⠀⠀

V = π r² h

⠀⠀⠀⠀

• Using equations formulae

⠀⠀⠀⠀

$\sf \dfrac{V}{\pi} = r² h$

⠀⠀⠀⠀

$\sf \dfrac{V}{\pi\times r^2} = h$

⠀⠀⠀⠀

• checking correct option

⠀⠀⠀⠀

Option 1 :

⠀⠀⠀⠀

$\sf \bigg( h = \dfrac{V}{\pi r^2} \bigg) \neq ( h = V - \pi r^2)$

⠀⠀⠀⠀

This option is not correct

⠀⠀⠀⠀

Option 2 :

⠀⠀⠀⠀

$\sf \bigg( h = \dfrac{V}{\pi r^2} \bigg)$ = $\sf \bigg( h = \dfrac{V}{\pi \times r^2} \bigg)$

⠀⠀⠀⠀

This option is correct

⠀⠀⠀⠀

Option 3 :

⠀⠀⠀⠀

$\sf \bigg( h = \dfrac{V}{\pi \times r^2} \bigg) \neq ( h = V\pi r² )$

⠀⠀⠀⠀

This option is not correct

⠀⠀⠀⠀

Option 4 :

⠀⠀⠀⠀

$\sf \bigg( h = \dfrac{V}{\pi \times r^2} \bigg) \neq ( h = V - \pi - r^2)$

⠀⠀⠀⠀

This option is not correct
