Question

A rectangular piece of paper 44cm long and 15cm wide is converted into a cylindrical by rolling if along its length find the volume of cylinder
​

Answer 1

Step-by-step explanation:

Here,

let b=15cm or height

length= 44cm or circumference of a circle

2πr=44cm

r=44cm/2π

=(22cm/22)×7

= 7cm

Vol= πr²h

= (22/7)×7cm×7cm×15cm

=( 22×7×15)cm³

=2310cm³
