Step-by-step explanation:

Find the volume of a cylinder, diameter 15, height 84, and divide that volume by 2.  That will be the capacity of the trough in cubic centimeters.  Divide that number by 1000, because there are 1000 cubic centimeters in a litre.   That will be the capacity of the trough in litres.
