The height and radius of a cone are each multiplied by 3. What effect does this have

Black_prince [1.1K]

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>

$\text {Volume of cone}=\frac{1}{3} \pi r^{2} h$

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

$\text {Volume of new cone}=\frac{1}{3} \pi(3 r)^{2}(3 h)=9 \pi r^{2} h$

original volume of cone x 27 = volume of new cone

Therefore, the original volume of cone is multiplied by 27
