Question

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

Answer 1

Answer:

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of a cone is given by the formula

$V=\frac{1}{3}\pi r^{2}h$

we have

$h=2x\ units\\r=x\ units$

substitute

$V=\frac{1}{3}\pi x^{2}(2x)$

$V=\frac{2}{3}\pi x^{3}\ units^3$
