441000 440700 440000 440400

Detailed Solution & Logic

Correct Answer:

440000

Wire is a cylinder
Diameter= 10 cm r = 5cm
Length = 56 m = 5600 cm
$ \pi = \dfrac{22}{7} $
Volume = $\pi r^2 h $
$ = \dfrac{22}{7} \times 5^2 \times 5600 $
$ = \dfrac{22}{7} \times 25 \times 5600 $
$ = 22 \times 25 \times 800 $
Answer = 440000
