Answer:

38.5cm^2

Step-by-step explanation:

=>Length of paper= Circumference of cylinder

11= 2πr

11= 2×22/7×r

r= 7/4 cm

=> Volume of cylinder= πr^2h

Volume of cylinder= 22/7×7/4×7/4

Volume of cylinder= 77/2

Volume of cylinder= 38.5 cm^2

Volume of cylinder= 38.5 cm^2

Given : A paper measures 11 cm by 4 cm. It is folded to make a cylinder. It has a height of 4 cm.

To Find : Find the volume of the cylinder ?

_________________________

Solution : The paper is folded, the length, 11 cm, will become the circumference of the cylinder.

~

  • Find the radius :

➻ Circumstance = 2πr

➻ 2πr = 11

➻ 11 ÷ 2π

1.75 cm

~

  • Find the volume :

➻ Volume = πr²h

➻ Volume = π(175)²(4)

Volume = 38.5 cm³

~

Hence,

  • The volume of the cylinder is 38.5 cm³.
