Question

a rectangular piece of a paper with dimension 22 cm × 10 cm is folded without overlapping to make the cylinder of height to 10 centimetre find the volume of cylinder​

Answer 1

Answer:

11 cm x 4 cm rectangular piece of paper is folded and taped without overlapping to make a cylinder of height 4 cm. Find the volume of 

Step-by-step explanation:

Height of cylinder=5

circumference of the circle of cylinder=22

2πr=22

πr=11

r=11×7÷22

r=7/2

volume of cylinder =πr^2h

=22/7×7/2×7/2×5

=22×7×7×5/28

=22×7×5/4

=11×7×5/2

=192.5cm^3

Answer 2

${\huge {\underline {\underline {\mathfrak {\red {Ånswer}}}}}}$

Height of cylinder=10

Circumference of the circle of cylinder=22 × 10

2πr=22 × 10

πr= 220 / 2

πr= 110

r=110 × 7/22

r=5 × 7

r= 35

_________________________

Volume of cylinder =πr^2h

=22/7×35×35×5

=22×7×5×5

=22×7×25

=22 × 175

= 3850 cm square.
