Cross-section 32163

The bottom of the garden pool of circular cross-section has an inner diameter of d = 4 m. The water depth is 0.8 m. How many liters of water can we fill into the pool?

Correct answer:

V =  10053 l

Step-by-step explanation:

$$\begin{gathered} d=4\text{m} \\ h=0.8\text{m} \\ r=d/2=4/2=2\text{m} \\ S=\pi \cdot r^2=3.1416\cdot 2^2\doteq 12.5664{\text{m}}^2 \\ {V}_1=S\cdot h=12.5664\cdot 0.8\doteq 10.0531{\text{m}}^3 \\ V=V_1\to \text{l}=V_1\cdot 1000\text{l}=10.0531\cdot 1000\text{l}=10053\text{l}=10053\text{l} \end{gathered}$$
