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 wide when the water is 2 ft deep, what is the diameter of the pipe?

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.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
