Question

Graph the radical equation that can be used to calculate the radius, r, of the tank. Use the lowercase "r" and the uppercase "V" when entering the equation. After the equation has been entered, set the value of pi to be 3.14.
and please explain how to use the graph and what should I type and where

Answer 1

Tank is made like Cylinder

So let's find r

• Radius=r
• height=h

$\\ \tt\hookrightarrow V=\pi r^2h$

$\\ \tt\hookrightarrow r^2=\dfrac{v}{h\pi}$

$\\ \tt\hookrightarrow r=\sqrt{\dfrac{v}{3.14h}}$

Answer 2

$V = \pi {r}^{2}h$

${r}^{2} = \frac{v}{h\pi}$

$r = \sqrt{ \frac{v}{3.14h} }$
