The height of a cylinder is twice the radius of its base.

What expression represents the volume of the cylinder, in cubic units?
a. 4piX^2
b. 2piX^3
c. piX^2 + 2x
d. 2 + X^3​

Respuesta :

The volume of a cylinder with radius [tex]r[/tex] and height [tex]h[/tex] is

[tex]V=\pi hr^2[/tex]

If the radius is [tex]x[/tex] and the height is [tex]2x[/tex] the formula becomes

[tex]V=\pi \cdot 2x\cdot x^2=2\pi x^3[/tex]
