First we need to know volume of cylinder,as cups are cylindrical .
Secondly, sink is half spehere,so volume of it is given=2000π/3in^3
So we need to know number of cups we scoop is going to equal to the volume of a sink,then only it will empty.

Fist cup has a diameter of 4 inch height 8 inch
Voulme of a cylinder=pi×r^2h
V=pi×2×8
V=32π
Now divide it to voulme of sink
Volume of sink/voulmeof a single cup
Numberof cup=2000π/3/32=20.48
We can take 21
Rest of part u can solve with the same method
