Find the volume cm\(^3\) of a wire of diameter 10 cm and length 56 m. (Take \(\pi= \frac{22}{7}\))

Wire is cylindrical in shape.

Volume of cylinder = $ \pi r^2 h $

Diameter = 10 cm

Radius = $10/2 = 5$ cm

Length = 56 m = $56 \times 100 = 5600$ cm

Now,

$V=\frac{22}{7}\times 5^2 \times 5600$

$=\frac{22}{7}\times 25 \times 5600$

$=22 \times 25 \times 800$

$=550 \times 800$

$=440000$ cm$^3$

$\therefore$ Correct Answer: 440000 ✅
