Solve the formula for x.
V=2πrx+6πr2

Sagot :

Answer:

x=−18.849556r2+v/6.283185r

Step-by-step explanation:

Step 1: Flip the equation.

18.849556r2+6.283185rx=v

Step 2: Add -18.849556r^2 to both sides.

18.849556r2+6.283185rx+−18.849556r2=v+−18.849556r2

0r 2+6.283185rx=−18.849556r2+v

Step 3: Divide both sides by 6.283185r. 0r2+6.283185rx/

6.283185r = −18.849556r2+v/6.283185r

x=−18.849556r2+v/6.283185r

Let's see

[tex]\\ \rm\Rrightarrow V=2\pi rx+6\pi r^2[/tex]

[tex]\\ \rm\Rrightarrow V=2\pi r(x+3r)[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{V}{2\pi r}=x+3r[/tex]

[tex]\\ \rm\Rrightarrow x=\dfrac{V}{2\pi r}-3r[/tex]
