The height of a cylinder is twice the radius of its base. What expression represents the volume of the cylinder, in

cubic units?

4pix2

2pix3

pix2+2x

2+pix3

The answer is 2pix3 or  

Step-by-step explanation:

This problem brothers on the mensuration of solid shapes, a cylinder.

we know that the expression for the volume of a cylinder is

let the radius r of the base be=  x

and the height h of the cylinder be =  2x

we can now solve the expression that represents the volume of the cylinder, in cubic  units.

0 is its x and y coordinate
