Consider a cylinder with height h=3x-4 and radius r=3x+2 Determine a simplified expression for the ratio of the volume of the cylinder to its surface area. Make a sketch of the cylinder

Respuesta :

Step-by-step explanation:

Given that,

The height of the cylinder, h = 3x-4

The radius of the cylinder, r = 3x+2

The volume of the cylinder is :

[tex]V=\pi r^2 h[/tex]

The surface area of the cylinder is :

[tex]A=2\pi r(r+h)[/tex]

The ratio of the volume of the cylinder to the surface area of the cylinder is :

[tex]\dfrac{V}{A}=\dfrac{\pi r^2h}{2\pi r(r+h)}\\\\\dfrac{V}{A}=\dfrac{rh}{2(r+h)}[/tex]

Put all the values,

[tex]\dfrac{V}{A}=\dfrac{(3x+2)(3x-4)}{2(3x+2+3x-4)}\\\\\dfrac{V}{A}=\dfrac{(3x+2)(3x-4)}{2(6x-2)}[/tex]

Hence, this is the required solution.
