Question

A rectangular piece of paper 11cm * 4cm flod without overlapping to make a cylinder of height 7cm , find the volume of cylinder

Answer 1

Answer:

Length of rectangle paper =11cm

Breath of the rectangle paper =4cm

So circumference of circular part of cylinder =2π r

So it is equal to length of paper (paper folded in shape of cylinder)

7=2 π r

r=7/2 π

R=1.11cm

Volume of cylinder = π r² h

H=4cm

R=1.11cm

Volume = 3.14x(1.11)²x4=15.48cm³

Step-by-step explanation:

hope it helps:-)

Answer 2

Answer:

67. 37

pls mark BRAINIEST

Step-by-step explanation:

rectangular piece length=11

breath=4

volume of cylinder= πr²h

22/7*7/4*7/4*7

ans= may be 67.37
