Question

A sheet measuring 44m × 11 m is folded along it's length 44 m to form a cylinder . Find the radius of this cylinder.

Answer 1

Answer:

7 m

Step-by-step explanation:

Given that a sheet measuring 44 m x 11 m is folded long its length

=> Circumference of the cylinder so formed will be the length if the sheet.

But given length of the sheet = 44 m

We know  that, if r is the radius of the cylinder, then circumference of the cylinder is given by

2πr = 44

=> r = 22/π (Considering π = 22/7)

=> r = 7 m (approximately).

Thus, radius of the cylinder is 7 m.
