Answer:

10) The curved surface area of a cylinder is 4400 cm² and the circumference of its base is 110 cm. Therefore the height of the cylinder is 39.99 cm . Put in the formula of volume of a cylinder . Therefore the height of the cylinder is 39.99 cm and volume of the cylinder is 38543.332 cm³

11) The whole length of the circular base = circumference of the circular base = 44 cm. Height of the cylinder = width of the rectangular paper = 20 cm. The volume of the cylinder = 154×20=3080 .
