Question

Q) find the perimeter of rectangular sheet if the curved surface area of hollow cylinder is 4375cm2 it is cut along its height and and form The rectangular sheet of width 35cm
​

Answer 1

ANSWER

Given, 

Curved surface area of a hollow cylinder =4375cm2

By cutting it from the height, it becomes a rectangular sheet whose width =35cm

So, the height of cylinder =35cm

And length of sheet =HeightArea=354375=125cm

Hence, perimeter of the sheet =2(l+b)=2×(125+35)=320cm

Answer 2

Answer:

Given,

Curved surface area of a hollow cylinder =4375cm

2

By cutting it from the height, it becomes a rectangular sheet whose width =35cm

So, the height of cylinder =35cm

And length of sheet =

Height

Area

=

35

4375

=125cm

Hence, perimeter of the sheet =2(l+b)=2×(125+35)=320cm
