Concrete 3321

The water in the well is dropped by one ring; the ring has an inner diameter of 110 cm and a height of 80 cm. How much water is left in the well?

The chutes are concrete rings forming the walls of the well.

Correct answer:

V =  760.2654 l

Step-by-step explanation:

$$\begin{gathered} r=110/2/10=\frac{11}{2}=5.5 \\ h=80/10=8 \\ V=\pi \cdot r^2\cdot h=3.1416\cdot 5.5^2\cdot 8=760.2654\text{l} \end{gathered}$$
