Cylinder-shaped 3455

82 hl of water/hour flows into the empty cylinder-shaped pool with a diameter of 5 m. To what height will the pool be filled if water flows for 4 hours?

Correct answer:

h =  1.6705 m

Step-by-step explanation:

$$\begin{gathered} D=5 \\ r=D/2=5/2=\frac{5}{2}=2.5 \\ S=\pi \cdot r^2=\pi \cdot {\frac{5}{2}}^2=3.1416\cdot 2.5^2\doteq 19.635 \\ V=8.200\cdot 4=32.8 \\ h=V/S=\frac{164}{5}/S=32.8/19.635=1.6705\text{m} \end{gathered}$$
