Question

The volume of a cylinder is 4πx3 cubic units and its height is x units.

Which expression represents the radius of the cylinder, in units?

Answer 1

2x

Explanation:

Volume:

The volume of a shape (e.g. cylinder) is the amount of space in the shape i.e. the cylinder, You also can use radius here is how to calculate the radius of the cylinder:

V = 4πx³

Volume of a cylinder is:V = πr²x

We have: πr²x = 4πx³

Divide: r² = 4x²

Take out Square Roots: r = 2x

R = 2x

Therefore, the answer to your problem is, R = 2x
