The sides of a square are initially 4 inches in length and increase at a constant rate 3 Inches per second. One corner of the square moves along a line at a speed of 2 inches per second for 5 seconds. During this time the square makes one complete revolution about , revolving at a constant rate and remaining always perpendicular to . Explain carefully how to compute the volume of the solid generated by the square. Carry out the computation you describe.
