Question

A rectangular piece of paper having length of 4.4 cm and breadth 1.5 cm is to be rolled along its length to form a right circular cylinder. find the height and volume of the right circular cylinder ​

Answer 1

Answer:

2πr=4.4. (rolled along breath)Find radius by solving.

H=1.5

V=πr^2h

Step-by-step explanation:

Answer 2

When a rectangle rolls along with its height  

Height of cylinder =4.4cm

Its width =1.5cm =2*π*r
so,

r=1.5/2*π

=0.24cm

Now,

So volume of cylinder =

π*r^2h=

22/7*0.24*0.24*4.4

=0.79sq cm
