Question

A rectangular sheet of paper 44 cm x 20 cm is rolled along its length and a cylinder is formed. Find the curved surface area of the cylinder.​

Answer 1

Answer:

Dimensions of the rectangle,

Length= 44cm

Breadth = 20cm

Since, the rectangle is rolled along its length, so the length becomes the circumference of the cylinder and breadth become the height of the cylinder.

Circumference = 2πr = 44cm

Height = 20 cm

Curved surface area of cylinder= 2πrh

= 44 × 20

= 880 sq.cm
