# Half-filled

A cylindrical pot with a diameter of 24 cm is half-filled with water. How many centimeters will the level rise if we add a liter of water to it?

Result

x =  2.21 cm

#### Solution:

$D=24 \ \text{cm} \ \\ V=1 \ l=1 \cdot \ 1000 \ cm^3=1000 \ cm^3 \ \\ \ \\ r=D/2=24/2=12 \ \text{cm} \ \\ S=\pi \cdot \ r^2=3.1416 \cdot \ 12^2 \doteq 452.3893 \ \text{cm}^2 \ \\ x=V/S=1000/452.3893 \doteq 2.2105 \doteq 2.21 \ \text{cm}$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
