i figured out a bunch of stuff but i don't know what to do:
Area=(pi)r 2 A=100ft 2 so... r= 5.64ft
You're on the right track most of the way but look at your last line: you have h = V/A and then an expression for dh/dt; you're not doing this step correctly and further you are not using the fact that V is constant.
If f(x) = c/x where c is a constant, what would d/dx(f(x)) = f'(x) be?
Now what happens if you want d/dt(f(x))?
