Question

A cylinder is 2 m long and has its diameter 1-4 cm. Around the curved surface of the cylinder a wire 0-5 cm in diameter has been wrapped so that it may cover it Find the length and volume of the wire.

Answer 1

Answer:

length: 2m =200cm

:

height=200cm

diameter: 1.4cm

radius: 0.7cm

volume: πr^2h

:22/7×0.7×0.7×200

22×7×2

:22×14

:300cm^2

the volume of the cylinder is 300cm^2

Answer 2

Answer:

A cylinder is 2 m long and has its diameter 1.4 cm.

Around the curved surface of the

cylinder a wire 0.5

cm in diameter has been wrapped.

To find :

The length and volume of the fire.

Solution:

length: 2m =200cm

height=200cm

diameter: 1.4cm

radius: 0.5cm

volume: Пr^2h

22/7×0.5×0.5×200

345.62cm^2

The volume of the cylinder is 345 62cm^2
