Question

a cylinder of curved surface area 1250m² is formed from a rectangular metallic sheet. find the dimensions of the rectangular sheet if its length is double its breadth.
​

Answer 1

Answer:

Step-by-step explanation:

Curved surface area of cylinder =2πrh

CSA=1250

Let bredth be X.

And length is double its bredth so 2x.

2*22/7*2x*X=1250

44/7*2x2(square)=1250

2x2=1250*7/44

X2=8750/88

X=√8750/√88(bredth)

Length=2*(√8750/√88)
