Question

Rectangular sheet of paper if perimeter is folded 22 cm without overlapping to make a cylinder of height 8 cm find the volume of the cylinder

Answer 1

Answer:

Length of rectangle paper =11cm

Breath - - - - - - - - - - - - - - - =4cm

So circumference of circular part of cylinder =2 pi r

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

7=2 pi r

r=7/2 pi

R=1.11cm

Volume of cylinder = pi r² h

H=4cm

R=1.11cm

Volume = 3.14x(1.11)²x4=15.48cm³
