Answer:

$\frac{dh}{dt}$ ≅ $0.286\frac{ft^{3} }{min}$

Step-by-step explanation:

$V=\frac{\pi }{3}r^{2}h$ ; rate of change $\frac{dV}{dt}=10\frac{ft^{3} }{min}$ , we must find the rate of change of the depth $\frac{dh}{dt} =?;h=8ft$

5h=12r; $V=\frac{\pi }{3}\({\((5h}/12} )} ^{2}h=\frac{\pi }{3}(\frac{25h^{2} }{144})h; V=\frac{25\pi h^{3}}{432}$ ; deriving $\frac{dV}{dt} = \frac{25\pi }{432}(3h^{2})\frac{dh}{dt}$ → $10=\frac{25\pi h^{2}}{144} \frac{dh}{dt}$ → h=8 then $\frac{dh}{dt}=\frac{1440}{25\pi 64}=\frac{9}{10\pi}$ ≅ 0.286 $\frac{ft^{3} }{min}$

Answer:
64

Explanation:
The square of any number can be obtained by multiplied the number by itself.
In other words:
square of x = x² = x * x

For the given, we want to get the square of 8. This means that we will multiply 8 by itself.
Therefore:
square of 8 = 8² = 8 * 8 = 64

Hope this helps :)
