Question

A rectangle piece of metal sheet 11 m x 4 m is folded without overlapping to make a cylinder of height 4 m. Find the volume of the cylinder?​

Answer 1

Answer:

Circumference of cylinder = 11m

2π r = 11

48

★4.0

r = 11 π*2

7

r = 11* r = 4 44 m

h = 4

Vol of cylinder = πr² h

=

22 *7 *7 *4

744 =38.5m³

So volume of cylinder is 38.5m³

Answer 2

Answer:

38.5cm

Step-by-step explanation:

Given a Rectangular piece of paper 11cm×4cm is folded without overlapping to make a cylinder of height 4 cm

The length of the paper becomes the circumference of the base of the cylinder and width becomes height.

Let radius of the cylinder=r and height=h

Circumference of the base of cylinder =2πr=11cm

⇒2× 722×r=11

∴r= 47cm

Now h=4cm

Volume of the cylinder (V)=πr 2 h
