<h2>Answer:</h2><h2>volume of the cylinder = 2π
</h2>
Step-by-step explanation:
The height of a cylinder is twice the radius of its base.
Let the height of the cylinder = 2x
Let the radius of the cylinder = x
By formula, volume of the cylinder = π h
here r = x, h = 2x
substituting the values in the equation, we get
volume of the cylinder = π h = π
(2x)
volume of the cylinder = 2π
