Answer:
The balanced equation for reaction of solid cesium with liquid water
= 2Cs + 2H2O → 2CsOH + H2
Explanation:
cesium react with liquid water to produce cesium hydroxide and hydrogen gas
that is 2 moles of Cs react 2 moles of H2O to form 2 moles CsOH and 1 of hydrogen gas
Answer:
10 yards

Hi there!
Area of a circle formula:
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
Plug in the area 78.5 yds:
![78.5=\pi r^2](https://tex.z-dn.net/?f=78.5%3D%5Cpi%20r%5E2)
Isolate <em>r</em>:
![\displaystyle\frac{78.5}{\pi} =r^2\\\\\sqrt{\displaystyle\frac{78.5}{\pi}} =r](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B78.5%7D%7B%5Cpi%7D%20%3Dr%5E2%5C%5C%5C%5C%5Csqrt%7B%5Cdisplaystyle%5Cfrac%7B78.5%7D%7B%5Cpi%7D%7D%20%3Dr)
The diameter of the pond is equal to double its radius:
![2\sqrt{\displaystyle\frac{78.5}{\pi}} =d](https://tex.z-dn.net/?f=2%5Csqrt%7B%5Cdisplaystyle%5Cfrac%7B78.5%7D%7B%5Cpi%7D%7D%20%3Dd)
![d = 9.9974\\d \approx 10](https://tex.z-dn.net/?f=d%20%3D%209.9974%5C%5Cd%20%5Capprox%2010)
Therefore, the diameter of the pond is approximately 10 yards.
I hope this helps!
