Answer:
x= 6
Step-by-step explanation:
Hello There!
It would be 4.667.
Hope This Helps You!
Good Luck :)
as the following pic you can see the answer.
#diameter is 8 so radius is 4
The volume of a cone is
V = (1/3)πr³
We are given with radius and the height of cone, so we can solve for the radius as function of water level using ratio and proportion
3/9 = r/h
r = h/3
Substituting
V = πh³/81
Taking the derivative
dV/dt = πh²/27 dh/dt
Solving for dh/dt given
dV/dt = 10 m³/s
and
h = 3 m
dh/dt = 9.55 m/s
Answer:
the right answer is option D. 0.5b
I just want you know that there is another easier method
