Question

a rectangular sheet of length 44cm and breadth 21cm is rolled into a cylinder along the length.find the total surface area and volume of the cylinder​

Answer 1

Answer:

Step-by-step explanation:    Thank you for asking this question. Here is your answer:

We know that the length of the rectangular sheet L = 44 cm

and the breadth of the rectangular sheet B =20 cm

The radius r of the cylinder=circumference of the base of cylinder

=

44=2x22/7r

44x7/44

r=7

and the height h of the cylinder =20cm

volume of cylinder will be π²h

V=22/7x7x7x20

V=22x7x20

V=3080cm³
