# The pot

The pot is a cylinder with a volume of V = 7l and an inner diameter of d = 20cm. Find its depth.

Result

h =  22.3 cm

#### Solution:

$V=7 \ l=7 \cdot \ 1000 \ cm^3=7000 \ cm^3 \ \\ d=20 \ \text{cm} \ \\ \ \\ r=d/2=20/2=10 \ \text{cm} \ \\ \ \\ S=\pi \cdot \ r^2=3.1416 \cdot \ 10^2 \doteq 314.1593 \ \text{cm}^2 \ \\ \ \\ h=V/S=7000/314.1593 \doteq 22.2817 \doteq 22.3 \ \text{cm}$
