As the cylinder is folded without overlapping,
Diameter of the base of cylinder=11m
Radius of the base of cylinder=1/2 of diameter=1/2×11=11/2=5.5m
A/Q:-
Breadth of the rect. sheet=Height of the cylinder=4m
Volume of the cylinder=πr^2h
=22/7×(5.5)^2×4
=22/7×30.25×4
=22/7×121
=22×17.2857143
=380.285715m^3
=380.3m^2(approx.)
