The value (in cm\(^3\)) of a wire of diameter 10 cm and length 56 m is: take \(\pi = \frac{22}{7}\)
10 सेमी व्यास और 56 मीटर लंबाई वाले एक तार का मान (सेमी\(^3\) में) है: \(\pi = \frac{22}{7}\) लें
Detailed Solution & Logic
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
