On a water ride at the amusement park, a rotating valve sprays water for 15 ft in all directions. What its the area of the circu

andreyandreev [35.5K]

The area is 3.14*r^2

The rotating valve would be in the center of the circular wet patch so if it's spraying in all directions, then 15 ft = radius. 

Now plug it in. 

3.14 x (15)^2 = 706.5 ft^2

The amount of water remaining in the pool is decreasing at a rate of

Gnom [1K]

The average rate of change has a relationship with slopes. In this way, we can write the slope of a line as follows:

$Slope=\frac{Change \ y}{Change \ x}$

As you can see in the graph, we have a straight line whose slope is negative. This slope as we have said is the Average Rate of Change we need to find. So, to find the slope of this line we must choose two points and compute the following formula:

$ARC=Slope=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}$

The two points can be:

$P_{1}(0,40) \ and \ P_{2}(10,0)$

So:

$ARC=\frac{0-40}{10-0} \\ \\ \therefore \boxed{ARC=-4 \ gallons \ per \ minutes}$

Finally, the conclusion is:

The amount of water remaining in the pool is decreasing at a rate of 4 gallons per minute
