Question

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

What expression represents the volume of the cylinder, in

cubic units?

47x

200x

rox? + 2x

2 + 3x3

Answer 1

6.284x³ cubic units

Explanation:

let the base radius = x

let height which is twice the base = 2x

volume of cylinder =
`\pi r^(2)h`

volume of cylinder = 3.142 × x² × 2x

volume of cylinder = 6.284x³ cubic units
