Question

a cylinder of curved surface area of 1250 m2 is formed from a rectangular metallic sheet to find the dimension of the rectangular sheet if its length is doubled its breadth

Answer 1

HEY MATE ^_^

In this cylinder, the height will be the breadth for the rectangle, and the circumference will be the length for the rectangle.

As we know,

2πr × h = 1250

Also,

2πr = 2×h

∴2h²=1250

⇒h²=625

⇒h=25m

∴r=25/π

   ≈7.96m
