Question

A rectangular piece of paper with 44cm long and 21 cm broad is rolled along its length to form a cylinder. The radius of the cylinder so formed is​

Answer 1

Answer:

length =44cm; breath = 16cm

As folded along it's length,it's height would be 16cm.

so 2 * 22/7 * r =44cm

r =44 * 7 / 2* 22

r = 7

volume of cylinder = 22/7 r 2 h

=22/7 *7* 7* 16

=2464 cm2
