(D) The sheet is rolled along its length.Let the radius of the cylinder be $r$.The length of the sheet becomes the circumference of the base of the cylinder.$2 \pi r = 22 \ m$$2 	imes \frac{22}{7} 	imes r = 22$$r = \frac{7}{2} \ m = 3.5 \ m$The breadth of the sheet becomes the height of the cylinder.$h = 8 \ m$The volume of the cylinder is given by $V = \pi r^2 h$.$V = \frac{22}{7} 	imes (3.5)^2 	imes 8$$V = \frac{22}{7} 	imes \frac{7}{2} 	imes \frac{7}{2} 	imes 8$$V = 11 	imes 7 	imes 4 = 308 \ m^3$.
