Step-by-step explanation:
since the triangles are congruent, then corresponding angles are congruent.
∠ B = ∠ F
∠ FCE ≅ ∠ BDA
∠ EFC ≅ ∠ ABD
∠ FEC ≅ ∠ BAD
note that the order of letters in Δ ABD follows the same order as those in Δ BDA
The volume of each container is: 25,133 
Given:
height of container (h) = 80 cm
diameter of container (d) = 20 cm
radius = half of diameter =
of 
Recall:
Volume of a cylinder = 
<em>Substitute the values into the formula:</em>
