Q. 8

A rectangular she

Answer :

Given: Length = 44 cm

Breadth = 20 cm

To find: TSA of cylinder.

Formula Used:

Circumference of circle = 2πr

TSA of cylinder = 2πr (h + r)


Dimensions of rectangular sheet of paper = 44cm × 20 cm

When this sheet of paper is rolled along its length:


Circumference of base thus form = 44 cm

Radius = 7 cm

Height = 20 cm

Total surface area of cylinder =
