Water lily

The father placed 4 containers with water lilies in the built pond. The containers had the shape of a cylinder with a diameter of 55 cm and a height of 27 cm. How many liters are all the water lily containers?

Final Answer:

V =  256.6 l

Step-by-step explanation:

$$\begin{gathered} n=4 \\ d=55\text{cm} \\ h=27\text{cm} \\ r=d/2=55/2=\frac{55}{2}=27.5\text{cm} \\ {V}_1=\pi \cdot r^2\cdot h=3.1416\cdot 27.5^2\cdot 27\doteq 64147.395{\text{cm}}^3 \\ {V}_2=n\cdot V_1=4\cdot 64147.395\doteq 256589.58{\text{cm}}^3 \\ V=V_2\to \text{l}=V_2:1000\text{l}=256589.58:1000\text{l}=256.6\text{l}=256.6\text{l} \end{gathered}$$
