Question

A rectangular piece of paper 22cm long and 12cm broad is rolled along its length to form a cylinder. Find the volume of the cylinder so formed.

Answer 1

Length of rectangular paper =22 cm

Breadth of rectangular paper=12 cm

Area of rectangular paper= 22*12=264 cm sq

Height of cylinder= 22cm ( because rectangular paper filled along length)

Curved surface area of cylinder = Area of rectangular paper

So Curved surface area of cylinder= 264 cm sq

Volume of cylinder= Curved surface area x height of cylinder

= 264*22 = 5808 cm sq

Answer 2

Answer:5808 cm sq.

Step-by-step explanation:

Length of rectangle=height of cylinder

Breadth of rectangle=circumference of cylinder

Area of rectangle=length*breadth

=22*12

=264 cm sq.

Curved surface area of cylinder=264 cm sq.

Volume of cylinder=curved surface area*height

=264*22

=5808cm sq.
