Question

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

What expression represents the volume of the cylinder, in

cubic units?

42

250x

Orx + 2x

O2 + x

Answer 1

= 2 pi x^3

Explanation:

radius = x

h = 2x

The volume of a cylinder is

V = pi r^2 h

= pi ( x) ^2 ( 2x)

= 2 pi x^3
