Question

A hollow metal cylinder of lateral surface area 4928 cm2 is cut along its height to form a
- rectangular sheet of width 8 cm. Find the length of the rectangular sheet.​

Answer 1

Answer:

since the cylinder is cut along its height,

the circumference of its base = width of a rectangular sheet ; i.e. 2πr= 44 cm.

Curved surface area of the cylinder=2πrh

Given,

2πrh = 4928 h

=4928 /2πr

= 4928 / 8

= 616.

The length of the the length of the rectangular sheat is 616 .
