Jar

The jar has the shape of a cylinder. Height of jar h = 8 cm, and jar diameter D is 8 cm. After rolling the pot, some water spilled, and the water level accurately reached half of the base. The water level makes a parabola with the same diameter. How to calculate how much water remains in the jar?

Correct answer:

V =  85.3333 cm³

Step-by-step explanation:

$$\begin{gathered} h=8\text{cm} \\ D=8\text{cm} \\ r=D/2=8/2=4\text{cm} \\ V=D^2\cdot \frac{h}{6}=8^2\cdot \frac{8}{6}=85.3333{\text{cm}}^3 \end{gathered}$$
