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

Anastasy [175]

Answer:

The answer to your question is r = 2x

Step-by-step explanation:

Volume of a cylinder = V = π r² h

r = radius

h = height = x

Volume = 4x³

Then

r² = $\frac{volume}{\pi h}$

r² = $\frac{4x^{3} }{\pi x}$

r² = 4x²

r = 2x
