Nadia designs a water ride and wants to use a half-cylindrical pipe in the construction. If she wants the waterway to be 8 ft w
ide when the water is 2 ft deep, what is the diameter of the pipe?

Answer:
<h2>8 feet</h2>Step-by-step explanation:
In the image attached you can observe a cross section of the half-cylindrical pipe.
So, if the pipe is 8 feet wide, that means its diameters is also 8 feet, because the wideness coincide with the distance from one point to an opposite point crossing through the center of the circumference.
Therefore, the diameter is 8 feet.

Consider the coordinate plane:
1. The origin is the point where Sharon and Jacob started - (0,0).
2. North - positive y-direction, south - negetive y-direction.
3. East - positive x-direction, west - negative x-direction.
Then,
- if Jacob walked 3 m north and then 4 m west, the point where he is now has coordinates (-4,3);
- if Sharon walked 5 m south and 12 m east, the point where she is now has coordinates (12,-5).
The distance between two points with coordinates and
can be calculated using formula
Therefore, the distance between Jacob and Sharon is
