The volume of the original cone is multiplied by 27
<h3><u>Solution:</u></h3>
We have been given that the height and radius of a cone are each multiplied by 3.
We need to find what effect it has on the volume of the cone.
<em><u>The volume of the original cone is given as follows:</u></em>

Now, the radius and height are multiplied by 3.
Therefore, the new radius is ‘3r’ and the new height is ‘3h’.
Hence the new volume is

original volume of cone x 27 = volume of new cone
Therefore, the original volume of cone is multiplied by 27
