Question

the curved surface area of a hollow cylinder is 4375 it is cut alongst its height and formed a rectangular sheet of width 35 m find perimemetr of rectangualr sheet​

Answer 1

Step-by-step explanation:

4375=2×22/7×17.5×h

h=40 approx

perimeter of rectangle=2(l+b)

=2(40+35)

110m

Answer 2

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(+b)=2×(125+35)=320cm
