Question

The volume of a cylinder is 4x3 cubic units and its height is x units.

Which expression represents the radius of the cylinder, in units?
2x
4x
2pi x²
4pi x2​

Answer 1

Answer:A

Explanation:

Answer 2

The answer to your question is r = 2x

Explanation:

Volume of a cylinder = V = π r² h

r = radius

h = height = x

Volume = 4x³

Then

r² =
`(volume)/(\pi h)`

r² =
`(4x^(3) )/(\pi x)`

r² = 4x²

r = 2x
