surface area of cylinder
area = pi*d*h
22/7*9.8*13.2
406.56 sq. cms.of paper is required.

You need to find the surface area of the sides of the can.
Imagine that this label, before being wrapped around the can would actually be a rectangle.
The area of a rectangle is its' height x width.
The height is 13.2 cm.
The width is the the length of the paper going around the can which is the circumference of the can.
The circumference of a circle is given by the equation pi x D where D is the diameter of the can which is pi x 9.8
So the answer is pi x 9.8 x 13.2
So the area of the paper required is 406.4 cm sq.
