# The cylindrical container

The container has a cylindrical shape the base diameter 0.8 meters has a content area of the base is equal to the content area of the shell. How many full liters of water can be poured maximally into the container?

Result

x =  100 l

#### Solution:

$D = 0.8 \ m \ \\ r = D/2 = 0.4 \ m = 4 \ dm \ \\ S_1 = S_2 \ \\ \pi r^2 = 2 \pi r h \ \\ r = 2 h \ \\ h = r/2 = 2 \ dm \ \\ V = \pi r^2 h = \pi 4^2 \cdot 2 = 100 \ \text { l }$
