what happens to the volume of a cone when the height is doubled

Volume of Cone =  (1/3) Pi * r^2 * h.When you double the height,  Volume =  (1/3) Pi * r^2 * 2h.                                                                    =  2 * (1/3) Pi * r^2 * hHence the volume would be doubled as well.

it would be doubled but you have to double height
