The height of sand in a cylindrical-shaped can drops 3 inches when 1 cubic foot of sand is poured out. What is the diameter, in inches, of the cylinder?

Given,


1 cubic feet =12×12×12 = 1728 inch3


Culinder of volume decrease = πr2×3 inch


= πr2×3 inches3 = 1728 inches3


= πr2 =


= =


Diameter of cylinder = 2r = 2×
