Use the geometric mean for right triangles here. Like this $\frac{9}{y}= \frac{y}{7}$ . Cross multiply to get $y^{2}=63$ , and $y= \sqrt{63}$ . That simplifies down to $y= \sqrt{9*7}$ . Pull out the 9 as a perfect square of 3 and you're left with $y=3 \sqrt{7}$ , first choice above.

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
