Consider the solid shaped like an ice cream cone that is bounded by the functions z=x2+y2√ and z=18−x2−y2√. set up an integral in cylindrical coordinates to find the volume of this ice cream cone.

Given:

The triangle ABC is reflected over the x-axis.

The distance between point A and A’ is 14.

To find:

The distance between the x-axis and A’.

Solution:

If a figure is reflected across the x-axis then the corresponding parts are mirror image of each other about the x-axis.

It means the distance between A and x-axis is same as the distance between x-axis and A'.

The distance between point A and A’ is 14.

Let d be the distance between the x-axis and A’. Then,

Therefore, the correct option is 1.
