Answer 2

The volume of the cylinder is 672 cm³.

• The length and breadth of the paper is 33 cm and 16 cm respectively.

• Now, the paper is folded around its breadth to form a cylinder.

• Therefore, the circumference of the base of a cylinder is equal to the breadth of the paper and the height of the cylinder will be equal to the length of the paper.

Circumference = 2πr

16 = 2×(22/7)×r

r = (28/11) cm

• Now, volume of the cylinder is given by

Volume of cylinder = πr²h

• Substituting the values r = (28/11) cm and h = 33 cm in the formula, we get

Volume = (22/7)×(28/11)²×33

Volume of the cylinder = 67 cubic cm.

• Volume of the cylinder is 67 cubic cm.
