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]
