Answer:
28 oz of water
Explanation:
Percentage of salt in the original solution = 15%
Let the amount of water to be evaporated = w
If we remove w oz of water from 70 oz solution, the resulting solution contains:
So, we have the equation:
We then solve for w:
Thus, 28 oz of water must be evaporated from a 70 oz, 15% saline solution to produce a 25% saline solution.

volume of cylinder = PI*r^2*h
r=11
h=15
using 3.14 for pi
3.14*11^2*15 = 5699.1 units^3
