The volume of the sink is 1072 in³.
One day, his sink clogged. He has to use one of two cylindrical cups to scoop the water out of the sink. The formula for determining the volume of a cylinder us expressed as
Volume = πr²h
Diameter of the cylindrical cup = 2inches
Radius = diameter/2
Radius of the cylindrical cup = 2/2 = 1 inch
