Question:

12/ 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 coverit completely. Find the length and volume of the wire.

Answer:

Given:

length:2m=200cm

height=200cm

diameter=1.4cm

radius=0.7cm

Formula

${\huge{\boxed{\mathcal{\red{2πr²}}}}}$

=22/7×0.7×0.7×200

=22×7×2

=22×14

=300cm²

The volume of the cylinder is 300cm²
