A cylinder container has a radius 5 cm and height 10 cm filled with water.

If a filled container weight is 2 kg.
What is the weight of the empty container ?

1 answer

volume = πr^2 h
= π(25)(10) cm^3
= appr 785.4 cm^3

by the beauty of the metric system, that would be .7854 kg of water

so the empty container weighs
2 - .7854 or aprr 1.21 kg
