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

A cylinder has a height of 2 x and a radius of x.

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

A cylinder has a height of 2 x and a radius of x.

What expression represents the volume of the cylinder, in cubic units?

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be .

Now we will use volume of cylinder formula to our given problem.

, where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

Therefore, our required volume expression would be .
