Jar

From the cylinder shaped jar after tilting spilled water so that the bottom of the jar reaches the water level accurately into half of the base. Height of jar h = 7 cm and a jar diameter D is 12 cm. How to calculate how much water remains in the jar?

Result

V =  168 cm3

Solution:

h=7 D=12 r=D/2=12/2=6 V=D2 h6=122 76=168 cm3h=7 \ \\ D=12 \ \\ r=D/2=12/2=6 \ \\ V=D^2 \cdot \ \dfrac{ h }{ 6 }=12^2 \cdot \ \dfrac{ 7 }{ 6 }=168 \ \text{cm}^3
