Find the volume cm\(^3\) of a wire of diameter 10 cm and length 56 m. (Take \(\pi= \frac{22}{7}\))
10 cm व्यास और 56 m लंबाई वाले किसी तार का आयतन cm\(^3\) ज्ञात कीजिए। (\(\pi= \frac{22}{7}\) लीजिए)
Detailed Solution & Logic
Correct Answer:
440000
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 ✅
