Question

a rectangular sheet of paper 44 cm into 20 cm is rolled along its length to form a scandal find the volume of the cylinder so form

Answer 1

Length of the rectangular sheet l=44cm

breadth of the rectangular sheet b =20cm

then, the radius r of the cylinder=circumference of the base of cylinder =2pir

44=2x22/7r

44x7/44=r

r=7

height h of the cylinder =20cm

volume of cylinder =πr^2h

V=22/7x7x7x20

V=22x7x20

V=3080cm^3

Hope it is helpful for u....

If yes then plz mark it as brainliest.....

Answer 2

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=22/7 x 7 x 7 x 20

V=22 x 7x 20

V= 3080 cm³

I hope this would help you
